This wasn´t a bug, I found out what was wrong. When I did the channel
search, the modulation was set to AUTO, but my DVB-C driver could not
handle this, thus no right QAM setting could be used and I had no lock.
I deleted the video source, added a new one, did a new channel search
with setting the modulation to QAM256 and it works now. People who get
no lock should make sure to chose the right modulation when doing a
channel scan. Maybe this hint could be added to the FAQ/Wiki.
