[linux-dvb] A/V sync issues with DVB-S

HI!

Is it normal, that every now and then (1-2 of 10 recordings), I get one
serious (suddenly 30 frames off) A/V sync problem with DVB-S?

I am seeing this with TT 1500 (budget_ci) and Nova-S Plus (cx88). I
tested kernel 2.6.23 and 2.6.25.

OK, when playing this recording with mplayer, I see no glitch and no
warnings.

But when I play it with MythTV, it stutters for a few seconds when it
tries to softly match the sync.

I haven't seen this with DVB-C, so I'd like to know if something is
wrong with my SAT system.

Any help would be greatly appreciated.

Thanks!

Thomas
