Non-standard special DVD formats:
DVD-VCD
is basicly a VCD authored on a DVD. DVD supports the VCD resolution but the audio has to be resampled to 48 khz. If the audio is resampled to 48 khz it is standard DVD-Video. Read more here how to make a such.
DVD-SVCD
is basicly a SVCD authored on a DVD. DVD do not supports the SVCD resolution but it may anyway work and the audio has to be resampled to 48 khz like the DVD-VCD. Read more here how to make a such and download a DVD Sample including a DVD-SVCD here.
DVD-MP3
is MP3s burned on a DVD but very few MP3 capable standalone DVD Players supports it because most Players verify DVD as DVD-Video only. Check our DVD Players list for compatibility.
DVD-ISO
is MPEG ,MPG, VOB files burned on a DVD without any DVD Authoring(making the vob,ifo files) but very few standalone DVD Players supports it because most Players verify DVD as DVD-Video only. Check our DVD Players list for compatibility.

DVD Write and read speeds
Single Layer(4.7GB) write speeds
1x (CLV) = about 58 minutes
2x (CLV) = about 29 minutes
2.4x (CLV) = about 24 minutes
4x (CLV) = about 14.5 minutes
6x (CLV/ZCLV) = about 10-12 minutes
8x (PCAV/ZCLV) = about 8-10 minutes
12x (PCAV/ZCLV) = about 6.5-7.5 minutes
16x (CAV/ZCLV) = about 6-7 minutes
Dual/Double Layer(8.5GB) write speeds
1x CLV = about 105 minutes
2.4x CLV = about 44 minutes
4x CLV = about 27 minutes
Single Layer (4.7GB) read speeds
6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes
8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes
12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes
16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes
* write speed time and read speed time is not the same because writing requires some extra steps and also does the faster writing above 6x usually use lower write speeds for some parts of the dvd. 4x DVD speed = 36x CD speed. See section 4.2 in the DVDDemystified FAQ here.

DVD Sizes
The DVD sizes can be a bit confusing. There are basicly 4 different DVD Sizes,
DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.
DVD-10, holds around 9 400 000 000 bytes and that is 8.75 computer GB. DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Double Sided Single Layered.
DVD-9, holds around 8 540 000 000 bytes and that is 7.95 computer GB. DVD+R supports this format. Also called Single Sided Dual Layered. This media is called DVD+R9, DVD+R DL or 8.5 GB Media.
DVD-18, holds around 17 080 000 000 bytes and that is 15.9 computer GB. DVD+R supports this format. Also called Double Sided Dual Layered.
* In the computer world is 1 KB data = 1024 bytes so 4 700 000 000 bytes / 1024 = 4 589 843KB / 1024 = 4482MB / 1024 = 4.37GB. See section 3.3 in the DVDDemystified FAQ here.
DVD+R/DVD+RW/DVD+R DL and DVD-R/DVD-RW exact sizes
DVD-R/DVD-RW = 4 706 074 624 bytes ( 4488 MB )
DVD+R/DVD+RW = 4 700 372 992 bytes ( 4482 MB )

DVD
DVD stands for Digital Versatile/Video Disc, DVDR stands for DVD Recordable and DVDRW for DVD ReWriteable. If you're familiar with regular audio/music CDs or regular DVD-Video discs, then you will know what a recordable DVD looks like. A recordable DVD stores up to 2 hours of very good quality DVD-Video, including several audio tracks in formats like stereo, Dolby Digital or DTS and also advanced menu systems, subtitles and still pictures that can be played by many standalone DVD Players and most computer DVD-ROMs. If you choose to lower the video quality it is possible to store several hours video on a recordable DVD using low bitrates and low resolution with video quality more like VHS, SVHS, SVCD, CVD or VCD. It is also possible to have up to 4.37* GB ordinary data or mix DVD-Video and data on a recordable DVD that can be played by most computer DVD-ROMs.
There are three competing DVD Recording standards, DVD-R/DVD-RW and DVD+R/DVD+RW have pretty similiar features and are compatible with many standalone DVD Players and most DVD-ROMs while DVD-RAM has less DVD Player and DVD-ROM compatibility but better recording features.
DVD-R and DVD-RW
DVD-R was the first DVD recording format released that was compatible with standalone DVD Players.
DVD-R is a non-rewriteable format and it is compatible with about 93% of all DVD Players and most DVD-ROMs.
DVD-RW is a rewriteable format and it is compatible with about 80% of all DVD Players and most DVD-ROMs.
DVD-R and DVD-RW supports single side 4.37 computer GB* DVDs(called DVD-5) and double sided 8.75 computer GB* DVDs(called DVD-10).
These formats are supported by DVDForum.
DVD+R and DVD+RW
DVD+R is a non-rewritable format and it is compatible with about 89% of all DVD Players and most DVD-ROMs.
DVD+RW is a rewritable format and is compatible with about 79% of all DVD Players and most DVD-ROMs.
DVD+R and DVD+RW supports single side 4.37 computer GB* DVDs(called DVD-5) and double side 8.75 computer GB* DVDs(called DVD-10).
These formats are supported by the DVD+RW Alliance.
DVD+R DL
DVD+R DL or called DVD+R9 is a Dual Layer writeable DVD+R. The dual layered discs can hold 7.95 computer GB* (called DVD-9) and dual layered double sides 15.9* computer GB (called dvd-18).
DVD-RAM
DVD-RAM has the best recording features but it is not compatible with most DVD-ROM drives and DVD-Video players. Think more of it as a removable hard disk. DVD-RAM is usually used in some DVD Recorders.
This format is supported by DVDForum.

If the Windows XP install was an upgrade from Windows 2000, you may instead receive the following error message on a blue screen while attempting to start Windows XP:
BAD_SYSTEM_CONFIG_INFO
STOP 0x00000074
CAUSE
This issue occurs because Windows XP did not exist when Windows 2000 was released. The Windows 2000 bootstrap loader files are not aware of the changes that have been made in Windows XP. The computer needs these changes to load Windows XP.
NOTE: If you attempt to install Windows 2000 in a different partition while the computer is running Windows XP, you may receive the following error message:
This CD-ROM is from an older version of Windows than the one you are presently using. Setup functionality from this disk will be disabled.
RESOLUTION
To work around this issue, start the computer in Windows 2000, and then copy the NTLDR and Ntdetect.com files from the I386 folder on the Windows XP CD-ROM to the root of the system drive.
Even though a workaround for this issue is described in this article, you can only perform a dual Startup when you install Windows XP in a different partition after you install Windows 2000.
STATUS
This behavior is by design. In general, products are not forward compatible with future products because the design updates of future versions are unknown.
MORE INFORMATION
If you want to start multiple operating systems, install each operating system in a different partition in the following order: 1. Microsoft Windows 95, Microsoft Windows 98, or Microsoft Windows Millennium Edition (Me)
2. Microsoft Windows NT 4.0
3. Microsoft Windows 2000
4. Microsoft Windows XP
If you do not want to start the computer in all the operating systems that are listed, skip the ones that you do not need. NOTE: Do not convert the hard disk from Basic Disk to Dynamic Disk until you install all of the operating systems that you intend to use. Once you convert the hard disk from Basic Disk to Dynamic Disk, you may be unable to install any other operating systems on that hard disk.

Read-Only USB Storage
If you've been concerned about the possibility that users in your Windows XP environment might plug in a USB storage key and walk away with hundreds of megabytes of proprietary corporate information, XP Service Pack 2 (SP 2) lets you make USB storage devices read only, removing the possibility of leaking data via a USB key. To configure USB storage for read only, perform the following steps:
1. Launch the registry editor.
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. You should see a key called StorageDevicePolicies. If it doesn't exist, create a new key with that name.
4. In the StorageDevicePolicy key, create a REG_DWORD value called WriteProtect.
5. Set the data value of WriteProtect to 1.
6. This value will make USB storage read only. To enable read/write over USB, set the value to 0.
7. Exit the editor.
Make sure that you aren't using other USB storage devices such as hard drives or a CD/DVD writer before you set this registry value.

Planet Alignment Could Crash Net
By Martin Stone, Newsbytes.
February 03, 2000
Doomsday forecasters have shifted their attention from the Millennium Bug, which proved to have little bite, to an extraterrestrial occurrence destined to take place May 5, when a cluster of planets will align with the Earth.
Some say the phenomenon has the potential of creating colossal cosmic forces which could severely impact our planet.
Occurring only once every 6,000 years or so, the rare alignment of Mercury, Venus, Mars, Jupiter, Saturn, the Earth, the Sun, and the Moon could cause a magnetic surge with the potential to crash power grids, blind satellites, and seriously disrupt radio and landline communications, taking the Internet down in the process.
However, not all astronomers agree that the so-called "grand alignment" will have an effect on terra firma. According to a Canadian newspaper report this week, John Mosely, an astronomer at the Griffith Observatory in Los Angeles, has proclaimed, "There will be no effect whatsoever. It's just complete nonsense." An astronomer at St. Mary's University in Halifax was blunter, calling the fears, "Just a load of crap."
But the same article, filed by the Canadian Press wire service and carried by Monday's Montreal Gazette newspaper, quoted Georgia-based futurist Richard Noone as saying the alignment could trigger a massive magnetic flux and a huge solar storm. "We're talking about a solar mass ejection in which a billion-tonne wave of super-hot, electrically charged gas is discharged from the Sun and crosses space like a giant tidal wave. It would crash into Earth's electromagnetic field at 620 miles a second."
As well as the communications systems wipeout, Noone predicts the cosmic event could produce a spectacular display of northern lights, which he said might be visible as far south as Florida.
Survival Center Website operator Craig Smith told Newsbytes, "Yes, the potential does exist. The big question is - but will it?" He refers to Noone's article "Are We Approaching the Abyss?" and quotes, "Past solar storms have caused incredible damage, including disruptions of radio, television, telephone, satellites, radar, power lines, power company grids and other sophisticated electronic technologies. These past solar storms will be mere blips of inconvenience to us, compared to The Storm of the Millennium coming this spring."
More of Noone's predictions can be found at http://rnoone.com .
However, Philip Plait, operator of an astronomy-focused Website, told Newsbytes, "There will be no natural ramifications whatsoever from this alignment. The gravitational and tidal effects are so puny that they will be unmeasurable. Last December's full Moon was unusually close. I did a quick calculation and showed that the gravity of that full Moon was much larger than the Moon and planets in this upcoming alignment. We weren't destroyed on Dec. 22, and we won't be in May.
"There won't be any electromagnetic effects either. The Sun is the only real contributor of these kinds of effects to the Earth. The sunspot cycle and therefore solar activity will be at a maximum this year. However, this has nothing to do with the alignment."
Plait has posted a wealth of grand alignment information on his site at http://www.badastronomy.co/bad/misc/planets.html .
Other doomsayers fear an extraordinary gravitational pull on our planet, which would wreak havoc in many ways, including causing the Earth's tilt to change, not to mention earthquakes and floods.
Many scientists anticipate a major solar disturbance this year but most insist the grand alignment will have no effect on solar storms, which occur in predictable 11-year cycles. Major storms and eruptions on the Sun's surface have been known to affect communications systems and are blamed for a province-wide blackout in Quebec in 1989.
Plait summed up the controversy by declaring, "There will be a lot of people trying to tell you something different than what I am saying here. Chances are, they're trying to sell something."

Unlocking WinXP's setupp.ini
WinXP's setupp.ini controls how the CD acts. IE is it an OEM version or retail? First, find your setupp.ini file in the i386 directory on your WinXP CD. Open it up, it'll look something like this:
ExtraData=707A667567736F696F697911AE7E05
Pid=55034000
The Pid value is what we're interested in. What's there now looks like a standard default. There are special numbers that determine if it's a retail, oem, or volume license edition. First, we break down that number into two parts. The first five digits determines how the CD will behave, ie is it a retail cd that lets you clean install or upgrade, or an oem cd that only lets you perform a clean install? The last three digits determines what CD key it will accept. You are able to mix and match these values. For example you could make a WinXP cd that acted like a retail cd, yet accepted OEM keys.
Now, for the actual values. Remember the first and last values are interchangable, but usually you'd keep them as a pair:
Retail = 51882 335
Volume License = 51883 270
OEM = 82503 OEM
So if you wanted a retail CD that took retail keys, the last line of your setupp.ini file would read:
Pid=51882335
And if you wanted a retail CD that took OEM keys, you'd use:
Pid=51882OEM
Note that this does NOT get rid of WinXP's activation. Changing the Pid to a Volume License will not bypass activation. You must have a volume license (corporate) key to do so.
Just some random screenshots:

Remove Saved Passwords
Windows XP offers the ability to save passwords for web sites and network resources. This can be very convenient as opposed to remembering and entering the username and password each time you need access, but it poses a security risk because anyone who has physical access to your computer would also be able to log into those sites using your saved credentials. While biometrics and other user authentication methods have become more widely used and accepted in recent years, the prevailing method of user athentication remains the username and password. Users have passwords to access their computer, shared network resources, web sites, business applications and other resources.
Different sites and applications have different policies regarding how to create the passwords and standard security practices suggest that users should use a different and unique password for each login. For many users it becomes unruly to recall the various usernames and passwords and they may write them down on a notepad in their desk drawer or put it on a sticky note on their monitor so they can remember them all. Of course, anyone else can also come along and read the passwords as well.
Windows XP offers users the ability to retain passwords so that the authentication information required to login is automatically pre-populated when the different sites or resources are accessed rather than the user having to enter them each time. Because this requires being logged into the computer in the first place it provides some convenience for the user while remaining more secure than writing everything on a sticky note on the monitor. Unfortunately, it is still counter-productive from a security perspective because anyone who sits down at the computer while it is logged in or gains access to your computer user account will subsequently be able to access all of the various sites and resources as if they were the user because of the cached login credentials.
Windows XP does not offer a very easy way to review or remove the saved passwords though. If you follow the steps below though you can access a graphical interface to add, remove or edit the saved passwords on a given system.
1. Click Start and select Run
2. In the Open field type "rundll32.exe keymgr.dll, KRShowKeyMgr"
3. Once the Stored Usernames and Passwords interface opens you can select any of the entries and select Properties to view the existing information
4. To remove a saved password you can select one of the entries and select Remove. A confirmation screen will appear. Click on OK and the account will be removed
5. You can add additional saved passwords as well by clicking on the Add button and entering the appropriate information
6. Repeat the steps above as needed to add, remove or edit saved passwords
7. When you are done using the interface click the Close button
