OK... that helps, thanks! So after a little more research, I found that Vegas doesnt read mpeg2 files? But, I realized I dont need vegas anyway, since that would require re-rendering. So I just need to synch my new audio with the old (ac3) audio in Audition, export as wav and it should line up in architect for the re-author, being sure not to re-render when creating the dvd files...

Let me know if I'm on the right track...
