[mythtv-users] Randomly corrupt video

Thx for the reply. I have no CAM Modul inside and only one DVB-C Card.
According to the logs i send in my first email, no error is reported
during recording. Only after the recording is finished
(FinishedRecording(Cool Runnings), ClearFlags(RecorderRunning,)) the
following errors occur:

2006-10-22 15:16:02.677 Found useful audio frame from stream 2

Which then later result in the PTS errors while mythtv is transcoding
the video.

Could this be an error of mythtv or just a problem with signal strength.
I read that a problem in signal strength results in a stream error in
the log.
