Channel change fails for software encoders since 7334.

[bjm <bjm@…>]

Starting Live TV successfully plays the current channel. Any attempt to change the chanel by entering a number, using up and down keys or selecting from the EPG causes the playback to freeze on the current frame for 14 seconds then go blank in 7334. Later versions eventually show a dialog for the video failure but the frontend does not recover and both the frontend anbd backend need to be restarted.

Up arrow should change the channel from the current 20 to the next 22.
The frontend shows a freeze frame from 20.
