This would break the other interesting feature, shut down VDR as soon as 
the playback ends. Also, this would require a long and visible warning 
that VDR will soon stop playback because of inactivity, so the user wont 
be confused by the sudden stop of the playback.

Maybe not switching off display while doing playback? It doesn't make 
much sense anyway to run playback invisible.

We had this discussion before, and since the majority of VDRs continues 
to display live video, I don't think that this should be part of VDR 
itself, and I don't really want to extend this patch into the deeper 
parts of cDevice.

To de-tune live devices, a plugin could display a still, like 
streamdev-server does, to free up devices.

Unneeded tuners get de-tuned. Provide there are unneeded tuners. (I know 
that my primary FF card tuner gets de-tuned if I play back a recording.)
