Not sure, if this may relate to your problem, but ..
I use xine plugin and every once in a while I had a short interruption of sound. Today I was tail-ing -f syslog for another reason and there was this little glitch again! Just a very short interruption with no sound. I spent several weekends to find out, why xine always tells me, that "fixing sound card drift". I was p***ed by my hardware, but now I found out, what cause the problem. It's my ntpd, that steps the clock on my VDR hardware. To fix this, I now start ntpd with the "-x" option.
For Reference from man ntpd: -x Ordinarily, if the time is to be adjusted more than 128 ms, it is stepped, not gradually slewed. This option forces the time to be slewed in all cases.
Regards, Martin

This problem is yet to be fixed to my understanding. Now I have a good recording (one episode from Lost) where this happens very often. The problem seems to be related to situations where the scene fades black before new scene. There is something strange in those situations..
If someone has the knowledge/talent to start debugging the problem I can put the recording available for downloading.
Well, I don't have knowledge for debugging, but I ran some tests. I took
few
minutes crop from a recording of same episodes and tried it with different AV7110 firmwares. (TT DVB-C FF 2.1 card)
I tested with VDR 1.4.3 and test_av app included in 22623 test firmware package, with firmwares 261a, 261f, 2622 and that test version 22623. Everytime playback stuttered and lost a/v sync after scene change
situation.
So I think this is more like dvb firmware/driver problem than VDR problem. However this is very annoying.
The only way i know how to fix that is to run your FF card with some kind of software playback (ie; xine). I wish we had a version of firmware that didn't have this problem.. or at least a way for it to recover itself.
Regards.
