Thanks largely to Isaac's ffmpeg update, I've now got some BB HD streams working in mythtv. I did however have to apply the hack below. No joy with live tv tonight though - segmentation faults every time:)
Performance wise, I have one recording that averages about 16 fps. Athlon xp 3000+ overclocked to 2.4ghz, 1 Gb RAM, FX6200.
