Now I have been using DVB 04.04.2003 for a couple of days (sind 5.4) and
have not seen any grafical errors anymore, very nice :)
btw. I am/have been using "vidmode=2 hw_sections=0" since driver 26.03.03

Audio/Video out of sync is gone here. Also pause/play on replay of AC3
recordings is very good - previous I sometimes had A/V out of sync. Good
work Oliver :)

Pro7 is quite stable - but ...

I have noticed a couple of times that the sound is "bibbering" (not sure if
this is the right description - german = "bebende stimmen"). It is in the
high tones - as if there are lots of small droptouts and bitstreamout would
repeat previous frames. But in the log there is nothing like "CRC error -
repeating last frame" or anything else.

On sonday I was recording "The Patriot" on Pro7 and another movie on the
second card. When watching the live picture on pro7 there was lots of CRC
dropouts - IIRC 137 CRC errors in 4-5 seconds. It did not matter if I
switched forth and back - still there.
I have a second pro7 line in channels.conf without AC3 APID. That had no
problems - audio was fine !?

Btw. am I the only one using bitstreamout and having problems ?

Greetings
Christian
