Sorry 'bout your hair :)

I'm trying your tip right now. I first got a message about mythbackend 
being unable to access the file /var/video/nfslockfile.lock. That one 
was trivial, I just did a chmod a+w on that file. Now, when I start 
mythbackend from Konsole, I get this message:

leif at bellevue ~ $ mythbackend
2005-07-29 16:09:21.776 New DB connection, total: 1
Starting up as the master server.
2005-07-29 16:09:21.782 New DB connection, total: 2
Error getting inputs for the capturecard.  Perhaps you have
forgotten to bind video sources to your card's inputs?
2005-07-29 16:09:21.789 Channel(/dev/v4l/video0): CheckChannel failed. 
Please verify channel "3" in the "setup" Channel Editor.

Starting mythfrontend and try to watch TV now, I get a black screen with 
the message "1: composite 0" appearing briefly in the upper left corner 
in large letters.

I guess that binding video sources to my card's inputs is easy when you 
know how to do it, but could you please give me a hint on that one too?
