Read herring on this - was nothing to do with VDR.
Problem with my nvidia accelerator driver on high-bandwidth streams causing dropped frames....

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) channels.conf: 1;Juice TV;T:602000:M64:C:XXXX:849:850:0:606:305:182:3:0 2;Sneak Peek;T:602000:M64:C:XXXX:4961:4964=eng:0:606:310:182:3:0 3;*Living;T:610000:M64:C:XXXX:513+129:651=eng:0:606:402:182:4:0 4;*UKTV;T:610000:M64:C:XXXX:515+131:653=eng:0:606:404:182:4:0 5;*National Geographic;T:626000:M64:C:XXXX:6031:6032=eng:0:606:603:182:6:0 6;MTV;T:626000:M64:C:XXXX:6041:6042:0:606:604:182:6:0 7;*Documentary;T:626000:M64:C:XXXX:6051:6052=eng:0:606:605:182:6:0 7;BBC;T:626000:M64:C:XXXX:6061:6062=eng:0:606:606:182:6:0 8;*CNN;T:626000:M64:C:XXXX:6071:6072=eng:0:606:607:182:6:0
Below is some of the logs in std-out

any ideas on this???
