[mythtv-users] VDPAU High CPU Usage

Hi guys,

I just can't seem to get my CPU usage down. Right now, on a Atom 330 (2
cores, hyperthreaded), I'm getting 82% CPU usage by mythbackend and 44% by
the frontend. I'm using a Happague HVR-950Q framegrabber, and encoding to
MPEG4. It's not much better using RTJPEG. The sound skips, and I get buffer
underrun errors in the frontend's log.

I've disabled realtime threads, I've tried VDPAU Slim profile, I just can't
find anything that'll work. I've told MythTV to use 2, 3 and 4 "cores" to
encode video, to no avail.
