This has gotten pretty far afield from the original topic, but it still my be of interest to the HTML WG. I can take this off list if the group prefers.

I'll decline to comment on the business decisions of Apple or Microsoft. That said, many video capture products emit MPEG-2. Having the MPEG-2 codec (and the MPEG-2 TS container) available means those products "just work" without third party drivers or applications. > I gather that Safari does not expose all QuickTime codecs to the Web, > though. Why expose MPEG-2? I think you have gathered incorrectly. The only "QuickTime codecs" we explicitly block are ones which do not make sense in a <video> element, such as application/pdf and text/plain, both of which QuickTime claims to support. Additionally, Safari will also support Ogg or WebM, provided a QuickTime component supporting that format is installed. -Jer
