The problem has definitely been able to be seen on the computer and on a tv screen from the dvd. I know what you mean by the slowing down effect with deinterlacing. That has happened to me when I have rendered an avi file in progressive scan but the video clips being rendered were interlaced. Thanks a lot for the advice. Whenever I go back home and turn on Vegas, I'll actually know what all those options are doing rather than just taking a guess.
