Cannot watch live TV

Post by klugja » Wed Feb 06, 2019 8:47 am

I just jumped up from 26 to 29 (saved and restored the database). I also changed kernels. I am using Ubuntu 18.04.

Instant recording works from MythTV. Kaffeine can show me live TV.

The error appears to be that "Recording already exists ...", when it did not.

I found previous posts on this, so I jacked up the debug level. The complaint is the Jump Buffer is too small on the Frontend:

I already tried changing the signal & tuning timeouts to 3 seconds and 10 seconds.

I had installed the PPA, but not installed the packages for mythtv, but maybe they installed automatically. I checked the version, and it is actually:

MythTV Version : v30.0

(Solved) Cannot watch live TV

Apparently the storage group setting for WatchTV was empty. It worked on my old level, but if there was a storage group setting, it was not carried forward. My database of recorded shows was carried forward.
