More info
SVCD stands for "Super VideoCD". A SVCD is very
similiar to a VCD, it has the capacity
to hold about 35-60 minutes on 74/80 min CDs of very good
quality full-motion video along with up to 2 stereo audio
tracks and also 4 selectable subtitles.
A SVCD can be played on many standalone DVD Players and of
course on all computers with a DVD-ROM or CD-ROM drive with
the help of a software based decoder / player. It is also
possible to use menus and chapters, similiar to DVDs, on a
SVCD and also simple photo album/slide shows with background
audio. The quality of a SVCD is much better than a VCD, especially
much more sharpen picture than a VCD because of the higher
resolution. But the quality depends how many minutes you choose
to store on a CD, less minutes/CD generally means higher quality.
SVCDs can be played on
- Many standalone DVD Players, check here
for compability list
- All CD-ROMa/DVD-ROMs can play SVCDs with a software
DVD/SVCD-Player
If your DVD Player does not support SVCD
you can try this VCD
header trick, it requires no reconverting which mean that
you do not lose any quality.

What is CVD then?
CVD is basicly the same as SVCD but with a lower video resolution.
Using a lower resolution you get more data for each pixel
which means less mpeg artifacts such as blockiness compared
to a SVCD with the same bitrate, but you will lose some sharpness.
Most SVCD capable standalone DVD Players supports CVD. Download
a CVD sample here. Read this
CVD article for more detailed info.
What is XSVCD then?
