Pavel,

The reason why you probably do not get picture on LNB1 is because you 
are still getting a stream from LNB0. Probably there is a transponder on 
LNB0 with the same frequency and symbolrate as on LNB1 (frequency 11515 
MHz H, symbolrate 27500000) but the specified PIDs (vpid 0x0947, apid 
0x0948) do not exist. Therefore you do not get a picture.

Have a look at http://nl.kingofsat.net/pos-19.2E.php. Find the 
transponder for LNB0 with the same frequency and symbolrate (frequency 
11515 MHz H, symbolrate 27500000) as tried on LNB1 but with a set of 
PIDs that exist on LNB0. Change the channels.conf file and szap again to 
LNB1 with these parameters. If you do get picture you are sure that the 
diseqc switch is not switching but stays on LNB0.

Please report your result to the list.

Regards,

Michel.
