I've recently added a dvb-c card, CI and Irdeto CAM to a system running
vdr-1.5.5. All channels are encrypted. Some channels (about 20%) seem to
have stuttering video. I only get a frame every 1/2 second or so - the
video freezes on a frame for 1/2-1 second, then moves to the next frame etc
etc.
There are no messages in /var/log/messages or kernel messages in dmesg.
The only difference in changing to one of the stuttering video channels is a
sequence of "aMMMMMAMM" messages in the stdout logs from vdr.
Below is the channels.conf. The channels 3 & 4 marked with '*' are examples
of the problem channels. The only common thing between all problem
channels, is they all have a separate PCR PID. But so do some of the
non-problem channels!
(symbol rates are XXXX'd out - as my provider protects these sorry)
