  Doesn't IE use directshow filters for playback? As long as anything like ffdshow or lavfilters is installed it could just use those. Afaik firefox uses system-provided h.264 decoders to support that since they don't want to ship one with firefox.

    Firefox ships their own decoder now, Cisco donated a license of the MPEG patents to Mozilla.
