For a simple video this is true. However, Windows Media and Real (not quicktime to my knowledge) support features that enable rich media applications though embedding in-band metadata alongside video data. As with any company, Microsoft and Real's objectives are to make money. They try to do this by offering products that have features not available with strict standard adherance. Pure MPEG4 does not support this metadata embedding (scripting) that allows for rich media presentations. In any case, linux machines can play windows media and real formats as well, though I doubt it can embed within a browser, and as a result I'm not sure if you can take advantage of scripting. I believe the link to mplayer was posted here earlier, but I'll post it again: http://www.mplayerhq.hu/homepage/design6/info.html Microsoft is planning the release of the Windows Media 9 format for public consumption (by standards bodies etc), so I would expect projects like mplayer to gain a lot of momentum and/or funding in the near future. Not sure about Real as I don't really follow their developments much (the helix server is a bit rich for my tastes). -Javier -----Original Message----- From: Shawn K.

MPEG is the most standard (I assume some of those PCs and Macs will be running Linux, too). Forget the Windows Media formats; Microsoft introduces things like this to further their own objectives, often at the expense of the users. Same for RealVideo or whatever it's called now. A 90 second video in MPEG1 should not run much over 2 megabytes. You might be able to get it down to 1.5 megabytes, but the quality might degrade a bit. -- Shawn K.
