[linux-dvb] Big zapping problem

[michal <michal@etc.cz>]

As I wrote yesterday, I have zapping problem with DVB driver and 
Nova-S-CI. It is very often locked stream on transporder with another 
polarization. I changed szap so, that it sends diseqc command several 
times. It's a little bit better now, but exact same changes to VDR have 
no effect.

But I discovered really strange behaviour today. I loaded dvb-kernel
(latest CVS) driver (I need it because of RC support with Nova-S-CI) and
with this druver I can't tune anything. There are Astra at LNB A and 
HotBird at LNB B. If I try to zap something, then allways is tuned 
frequency about 860 Mhz lower and allways on HotBird :((  Examples are 
shown below.

Whats wrong?
