Here's one I used to convert an xvid encoded .avi to .mpg for the same reason.
http://www.snapfiles.com/get/internetvideoconverter.html It only took 5 minutes to convert a 30 minute file.
It converts between Mpeg (vcd/svcd/dvd compliant), DV, Quicktime, Windows Media, Xvid, H264, 3GP, PSP, iPod, Flash video (FLV, Swf) got from Youtube, DailyMotion, Google Video etc.
If all works as good as my conversion did this will be the Ifranview of video.
