I was running mythtv today at 480x480...video capture quality of about =
230 and a mp3 quality of 4 w/ my celeron 1.7 Ghz. The system was running =
fine at about 72% CPU load for about 40 minutes before I started getting =
the message on the console:


"audio running behind..."
"no more audio buffers :-("

(I got a lot more of the above)


eventually the picture locked.....I am assuming this is just because the =
CPU was too high and the audio encoding lagged behind enough to lock the =
picture. Am I correct? I didn't have time to reduce the system =
load/resolution and try again. Anyone else have this happen?

Isaac: What resolution are you running your mythtv? Any problems at =
higher resolutions?=20



Some more stats on my machine in case you're interested:


@ 640x480....system CPU runs at 95-97%
@ 480x480....system CPU runs at 70-73%
@ 352x240....system CPU runs at 8-10%

more stats later.


thanks,
Chris
