Thanks to Erica: "You can buy the MPEG playback codec from apple." and to Mark: "Apple's $20 MPEG-2 playback component will allow MPEG-2 playback from Mac OS 9 or 0S X (but you'll have to pay separately for each OS). If you're on OS X, you can also try a free MPEG-2 player like VLC: http://www.videolan.org/vlc/download-macosx.html VLC will allow simple playback, but none of the other cool things that QuickTime allows, like converting to a different QuickTime format (codec)." I'm on my way ..... Alan
