It depends on the startchan, that was set for initial tuning. If it fails to 
tune from the startchan it does always fail to the channels. The channels may 
work with other startchans. I noticed with some revisions, that i was able to 
tune to channels where i do not need a working diseqc (low band).

Should this be with current head, too? If not i have to recheck this with 
r10132. In current head there was the message Tune(): ... successfull ..
I inserted parts of the logfile in my message from "Mon, 28 Aug 2006 15:44:31 
+0200".

I am using 2x Skystar2 there were no messages in kernel logs.
