I'd be very happy playing HD DVB-T content recorded by Myth TV. The most intensive HD content being being digitally broadcast in New Zealand is 1080i H264 with LATM AAC audio. Most channels are 720p H264.
The AAC audio decoding is quite CPU intensive and I've only managed to playback 1080i without massive audio lag by turning on the skiploopfilter and setting it to 32, which drops all sorts of stuff. Can definitely notice the square blocks being redrawn as the content plays.
And, with the skiploopfilter turned on, XBMC is also dropping content for 720p files, which would otherwise have worked fine without it turned on.
I'm running an ASUS M3A78-EM board (ATI HD 3200 with HDMI) with an AMD X2 6000+ CPU. At 3.0Ghz, 2 cores and 125W, needing anything more grunty is getting damn pricey (fastest chip I could buy regardless of price at the time).
I'm hoping that ATI are also going to support VDPAU, but who knows what they are going to do...
