Have a video I created of a concert that I'm trying to get to SVCD. I have read just about all of www.vcdhelp.com and I can't find the answer to my question.

When I export the show, it has a frame size of 720 x 480. After it's complete, it's a considerably large .avi file.

When I put that in LSX Encoder or TMPGEnc, it won't open the file, as it says it's unsupported.

Do I need to change the framesize to 480 x 480 for it to work?

I'm able to create an SVCD by putting the .avi into Nero, although, I'm going to need to do the VCD Header trick to get the SVCD to play in my DVD player. Is there a way of extracting the SVCD Mpeg from the burned disc to do the header trick and then reburning on a different disc?
