I am using an MX-440 for *HDTV* output (on my dev machine), which is a
lot more demanding, with no real problems. Can you try renicing (-10 or
so) your X server, and -2 or so your mythfrontend?
How about your encoder settings? If the bitrate is too high you'll
consume a lot of CPU doing decoding, with not enough left for proper
output. Is your *system* fast enough? Is the CPU pegged when doing
Also try turning on Extra Audio Buffering.
OpenGL vsync is a lot more accurate than the old sleep/busywait method,
but should be virtually identical to the old Experimental AV Sync
option. Get it working and your problems should be solved.
