i downloaded the mac version of xvid 0.5.1 from xvid.org, and tried to play a movie with quicktime. it crashed. i looked for another version, and went to versiontracker and downloaded it's xvid codec. it plays only the first few seconds of the video, half scrambled and no sound, and then hanged. it annoyes me about this. i deleted the xvid codec, and tried 3vix. same result as the codec from versiontracker, and obviously the divx codec dosen't help at all. it's annoying that I have lots of xvid videos on my ibook now, and i just wanted to view it in quicktime. i tried vlc, mplayer, and xine before. I wasen't used to it's more complicated two window interface.
