[mythtv] Failed DVB recording

My email from March 25 is inserted below. It was the timeout you mention. I 
didn't get any response to that email but I am more relieved now than I was 
30 minutes ago. This is obviously a coding issue and not my hardware :P
 FWIW, It happened on the 25 March and on the 2nd April. A simply restart of 
the BE was all that was required once I realised the recording wasn't going 
to work.

 Email from March 25:
 For some reason my DVB#0 card couldn't tune to channel 10 tonight. It
had been recording stuff earlier in the day just fine but for some
reason it couldn't record Idol tonight. When I went to watch live TV,
the second card tuned straight to channel 10, no probs.

After playing with the ariel feeds, and still being unable to get it
working, I restarted mythbackend and both cards are working dandy now.
The errors I recieved in the log file were just what I expected...
