Hello, thanks for the reply. I just change the playback profile to
cpu+, but I am having more stops on the playback. I have latest Nvidia
drivers:

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86 Kernel Module  280.13  Wed Jul 27
16:55:43 PDT 2011
GCC version:  gcc version 4.4.5 (Debian 4.4.5-8)

I am monitoring the satellite signal (femon) and there is no
correlation with mythfrontend problems, the playback is SD, so there
is no heavy work to do.

I have two Nvidia ION based MythTV system, both backend/frontend with
same problems. This is an other log:

It looks that there is a audio problem, but I don't know how to handle it.

How can I know the audio and video bitrate/codec?

Thanks and kind regards.
