With the latest round of patches sat-sun hi res HDTV appears to be
somewhat broken. non-HD shows plays fine but when watching a HD show
not only is the video ~1/4th speed, but audio is running even slower
(all sounds are lower pitch, drag on, the old "slo-mo" effect.
CPU's running well below capability.
I'm running off of OSS, rather than ALSA right now. Using XvMC of
course. Tried everything I could think of. Possibly a timing issue.
Not sure if it came through with this patch or another..
