I just tried the CVS. I do not get the infinite loop any longer, but
still experience some strange behaviour.

The tuning still is trying to access the wrong frequency once. This
causes  some of the channels to be discovered twice. Scan however stops
after discovering those. As you can see, scan discovers a total of 19
channels. In fact I can only see 15 channels. 4 channels are discovered
twice with slightly different settings in channels.conf, differing in
the second FEC value.

Thanks for the help,

Christoph
