Every time I have used TMPGenc or Main-Concept lately to create an SVCD, it has created a 640x480 mpg rather than 480x480, even though I have specified 480x480 in some cases. It worked at one time with smaller files, several months ago. Obviously this is a problem when I get to Nero to burn it or try to play the mpg straight off a disc. It doesn't appear to be an SVCD. Any ideas?

Hopefully this is something simple and stupid.... ; )
