 I scanned for new channels using mythtv setup. I watched some of the new
 ones to see what they were and decided to delete some of them using
 mythweb.

 When selecting live tv it fails and dumps me back at the main menu. Log
 file looks like this:

 I suggest that this failure cause mythtv to select the next, or previous
 channel instead of giving up, or perhaps display a blank screen and let
 the user change channel or input. This may sound like a feature request,
 but I had to hack the database to make one of my existing channels 93, go
 to live tv, change to an existing channel, then roll-back the database, so
 this feels more like a bug.
