I doubt it's only the signal handling. It looks like a
synchronization problem to me. It seems vdr tries to play the
recording and display the still picture at the same time when
jumping between cutmarks. I added some LOCK_THREAD into cDvbDevice
functions, that makes at least the displayed garbage go away but
there are still hangs or even deadlocks.
