Sound's like a missing codec, this should play it: http://www.afterdawn.com/software/video_software/codecs_and_filters/xvid.cfm Latst version is 1.3.1,I think or Kazza Lite codec pack should contain all you need (Full and no relation to Kazza). Codec's can conflict so one or the other. VLC player will play it too.
Fantastic, now i tried to put this on a disc with roxio 9, i took 5 hours and at the end there was a disc error, can this be put on a disc? dvdscr.Xvid-orc thanks for your kind help.
Not familiar with Roxio, try DVD Flick (free): http://beginwithsoftware.com/videoguides/dvd-flick-guide.html ImgBurn is free and is the best burner available free or paid.
