LiveTV works as continuous recordings of listed programmes. If there is
no prog listing EPG then recordings stop/start on the hour & half hour.
That causes a playback glitch especially if you run close to real-time.

Watching an active recording (here) has a glitch when the recording
stops. This started from 0.27, seems related to flood of mysql queries.

LiveTV on an HLS channel just crashes the FE on the hour & half hour.
