I have this HTPC setup with a AMD Fusion in it (E-350) running Archlinux and XBMC. Without hardware acceleration it's possible to play 720p but just barely. With xvba-video (thanx to splitted desktop systems) it works like a charm with just a few percentage cpu usage and tear free playback!

So here i praise you 2 (AMD for XvBA and E-350) and Splitted desktop systems for making a VAAPI backend. It really works well on my HTPC. Thanx a lot and keep up the good work!
