I can record TV with MythTV, and I can watch TV with Caffeine.

I backed up my database, and restored first to .29, then to .30 with
Ubuntu PPA, and neither work with WatchTV.

I tried increasing the signal timeouts to 3 and 10 seconds. The WatchTV
fails in less than 1 second.

Frontend complains the buffer file is to small (0B). I tried increasing
it with mythtv-setup and it is not 0 bytes. That did not help anyway.

The backend says something about expiring some program that I am not
attempting to watch, though it is on the same channel I think.

Comment (by Peter Bennett):

Please check your storage group for LiveTV. Perhaps it is set to an
invalid directory.

Comment (by jaklug):

The storage group setting was empty. Either it wasn't carried forward, or
did not exist in my old level. Error handling could be more clear here.

Thanks.
