I'm not sure whether the driver plays all the data sent if the data stream
ends at some point. This might be the same problem as with the still pictures.
Maybe we need to repeat the last frame several times until the buffers are
flushed.

Take a look into recording.c, function RemoveDeletedRecordings() to see how and when 
VDR actually removes files. One condition is that the recording needs to be older
than 1 hour before it is deleted. These things are no "black magic", but just some
thing I did to attempt that an actual file removal is done when the system is
idle.

That depends mainly on the performance of your disk. Removing a file while
recording may or may not interfere with the recording. I'm afraid that's
all I can say.
