Quicktime 7 -> and MPEG4 are one and the same thing. You can knock Apple if you want but they invented desktop video back in the early 1990s. I think you should be thanking them instead for making desktop video possible. In the corner of my home office I have a an AV Mac that is dated 1993 - just think of what kind of video you could play back on a PC or under Linux then... Tony
