Watch TV fails after Myth Upgrade

[jaklug]

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.

The problem is 100% reproducible.

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

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.
