However, I was able to play back HDTV adequately using an onboard gf4mx w/the 
same processor. My current setup w/an FX 5200 is a bit smoother, but the 
gf4mx wasn't anywhere near as bad as that once I got it working. I did see 
similar behavior (fine for the first second or two, then choppy), but that 
was actually an ALSA problem. ALSA 1.0.6 caused major issues for me, which 
all went away both when downgrading to 1.0.5a and bumping up to 1.0.7.
