[linux-dvb] Re: Still A/V sync problems (PCR error?)

["Y2 Plugh" <y2_plugh@hotmail.com>]

Oliver and Johannes, thanks for spending time on this problem.

Yesterday evening I tried to recreate the problem, but at fiirst I did not 
succeed :-(
Everything was as it should be.
My first thougth was that it was because our provider did some work on it's 
transponders
in the evening from 4-5 november.
And that somehow he solved the problem.

I started doing something else, and just before I had to go te bed, I tested 
again, and
the problem was back. Unfortunatly I could not spend any more time on it.
I just managed to reload the driver and test again, the problem was still 
there.
(The PC is on 24/7, so I do not believe heat or something like that is the 
problem).

Yep, this is in "oke" mode,
In "error mode" the STC jumps also in between (my STC loop is 
usleep(100000), then I see
every few lines a "jump"

Autopid will set PCR, but after playback has started ??
Anyway, I "deleted the autopid pid setting" during my tests (getavpid also 
didn't show PCR pids
changing).

I will again try to break down this problem in smaller pieces (not tonight, 
no time):
vanilla VDR
FTA channel (if possible)
Find the "trigger".
More ideas ???

Greetings Rene
