VCD: the oldest of the video-on-cd formats.. 'VHS quality'
1150 kbit/s MPEG-1
352x288x25fps res (PAL) or
352x240x29.97fps (NTSC) or
352x240x23.976 fps (NTSC FILM)
audio for all is 224 kbit/s MPEG-1 Layer 2, 44.1khz 16 bit stereo
SVCD: a newer 'upgrade' of VCD.. quality somewhere between laserdisc and dvd..
Video:
Max of about 2600 kbit/s MPEG-2 (CBR or VBR)
480x576 at 25 fps (PAL) or
480x480 at 29.97 fps (NTSC)
with up to 4 subtitles
audio can be from 32-384 kbit/s MPEG1 Layer 2 or MPEG 2
there are also such animals as XVCD and XSVCD (x for xtended).. these are really just putting a higher bitrate stream on an (s)vcd disk (ie a dvd-like mpeg2 stream on an svcd disc)... there are a handful of players that will play it back.. most will bomb.. (why you want 5 minutes of dvd quality video on a cd is beyond me, but people do it)
either VCD or SVCD support menus and still pics and some other funky doodle crap..
avi, asf, divx, ra, rm, quicktime, motion jpeg, cinepak etc etc etc are all *not* vcd, thou you can always reencode.. a task requiring lots of a) hard drive, b) cpu, c) memory and d) PATIENCE
for all the info you'd ever want about encoding/burning/capturing/creating vcd/svcd/dvd, go to

there are a couple true vcd players for dc.. i know the one i tried sucks hard and freezes on multitrack discs, theres supposedly a new one which partially works through a dongle that plugs into a controller port.. i have no idea about this one, if anyone knows, please share..
now, heres my questions for anyone who has a vcd card for saturn, or the vcd bootleg addon for psx.. does it/they play svcds?
