what player do you have ? Have you confirmed that this player is capable of playing SVCD ?
Maybe it's the SVCD itself. The correct way is with the MPEG2 folder, not MPEGAV. I don't know how you burn the SVCD, but try it with the other folder.
I am not sure what a CVD is but I think it's DVD content on a CD, a mini DVD.
All's right with the world when your PC is working right.
