[linux-dvb] knc1 dvb-s: bad streams on some channels

[Benjamin Greiner]

Hi,

I think I need your help.

I'm running a KNC-1 DVB-S Budget Card with the budget-av driver from kernel 
2.6.12(-gentoo-r6) but I have tried with kernel-included and CVS versions of 
the drivers since 2.6.8

Some channels work pretty fine (ProSieben, KABEL1, SAT1, DSF) but others show 
ugly fragments in their streams. In some programs they appear only 
occasionally (e.g "Das Erste" most of the time) some are unwatchable (ARTE, 
Eurosport, ZDF, RTL...)

Strange thing is: My brother has the same card on same distribution and it 
works on all channels. On the other hand it can't be a hardware problem, 
because my card works all fine on Windows.

Here is some logging output. I can provide recorded example streams if 
requested.

output of dmesg:
...
saa7146: register extension 'budget dvb /w video in'.

Would be glad to solve this problem together.
