Any MPEG2 renders (Main Concept) I do, other than "Default" import into Vegas fine, but only play sound in other players, or don't play at all. Does this sound like a codec issue?
Extensions are all .mpg - rendered five files with the same default setting. One plays, the rest either play audio with no video or get an error message in QT that they aren't movie files.
I'm gonna try to render out in V7 and see if that helps at all.

EDIT: Rendered in V7 got the same results - nothing in WMP, Audio only in another player, Error in QT. But rendering Main Concept MPEG1 works fine.
Do you have any DVD player software installed on your computer?
Are you rendering to separate MPEG-2 & AC-3 streams or ...?
Try Media Player Classic or VLC media player.
