Actually I was incorrect with this observation. If I let the
mythfrontend run for some time it spikes up to 92% CPU even if the video
out on the i819 is used.
I do see prebuffering messages constantly, like every second when the
PVR-350 is used for the output to the TV but if the i810 is used.
Could this be because the backend is too slow or too fast when the
PVR-350 is used? Is there a way to tune around this? Others have to
running with similar configs, so hopefully I don't need to upgrade the
box to something with a faster CPU. It seems to me the video quality
is a bit better with the PVR output vs. the i810 video quality.
Thanks,
