It can, but the deffenition of supported h264 formats is tiny, you have better luck just running divx/xvid. The ps3 has better defined rules for h264 and thuss even support 95% of the mkv files on the net (but you need to remux the header and perhaps audio, but that thats max 5 min on a 300$ system).

Windows 7 has support for divx/xvid now aswell as newer formats like mp4/h264 and even x264 but for mayority of those you need haali media splitter but the video in it self is supported AND accelerated (by the videocard if you got one that support DXVA)

Ehm, they told me (in school) that swedish belongs to the most hard to learn languages in the world. Now if thats truth or not i dont know, but one fact remains: we do have some unusual grammar. But for me english and swedish is just as good (or bad), so its just the same for me.
