Description
While running current trunk (20682) changing channels frequently causes the frontend to exit playback. In this particular case the backend never creates the actual recording although it appears the dummy recording exists.

Two test patches attached. Both are not in their final states, they contain extra debugging.
This could help both DVB and HD PVR LiveTV users (other DTV recorders not done yet).
If you test please report success/failure and post backend log with -v record.

(In [20733]) Refs #6612. Fix for NVP video_actually_paused state flutter.
When paused, the video_actually_paused variable was set to false at the top of NVP::DisplayNormalFrame?() then immediately set to true in DisplayPauseFrame?(). Fix by having DisplayNormalFrame?() set it based on paused variable.
Also, do not check PrebufferEnoughFrames?() when paused, this could consume all or most of our prebuffering attempts and then we fail (too) early when the file becomes available, this is more prevalent in LiveTV.
Thanks to elmojo, stuarta and GreyFoxx? for testing.
