Almost all boards including the low-end ones have HD Audio card nowadays to which they can attach a 5.1 sound speakers or 5.1 headphones. I predict 5.1 headphones will become quite popular in days to come. I think Silverlight should support 5.1 AC3 sound for true HD quality web video.
Sure. I meant the percentage of people who actually have 5.1 speakers and are configured to use them.

Even for those with the right hardware, how many wind up being stuck in stereo mode after a Soundblaster driver update :)?

Flash 9 just used hardware acceleration for scaling up the final composite to full screen in full screen mode.

Flash 10 is adding hardware compositing for bitmaps, IIRC (not vectors, though).

So, it's "hardware accelerated" playback but not in the decoders themselves. This frees up some CPU for decode, but a software decode can easily remain the long pole.
