While this *does* seem like something pretty basic to do, Apple's implementation loses the audio -- it's done this since QuickTime supported MPEG-1 playback as well. I don't know why, but that's the way it is, and yes it *does* suck. If you're running Mac OS X, there are some shareware and freeware utilities that will handle the audio conversion for you... I would do a search on macupdate.com (MUCH better than VersionTracker, IMO) for various strings: "MPEG2" "MPEG-2" "MPEG audio" I think MissingMpegEdit should do it: http://homepage.mac.com/rnc/ If the audio is in AC3 format (no, not AAC -- AC3 is the standard audio codec for DVD MPEG-2) you can use Mac3dec (search on macupdate.com again): http://sourceforge.net/projects/mac3dec/ Give that a go. > I just upgraded to Quicktime 6 and bought the Pro license and bought and > downloaded the MPEG2 component for playback of these files.
