I can't see why Flash should need *any* HW accell to do video playback. A while back, I investigated performance of Flash on Linux and Windows, and mplayer on the same. I found that mplayer's *unaccelerated* [0] fullscreen playback of a particular HD video scraped from YouTube was 80-90% faster than doing the same with the latest Windows-based Flash plugin.
tl;dr: Flash *SUCKS* for video playback.
I *really* wish that my google-fu was not so weak today... I'd love to find the comment where I detailed all of this.
[0] x11 video out under Linux and -IIRC- directx:noaccel under Windows.
