Hello!
Thanks for the patch and your time, i think we're on the way ;-)
The cutting process now works without segfaulting or unbehavior exit
of the vdr process itself - but during cutting i got A LOT of "frame
larger than buffer" x greater then 8 (8 is fix in all messages).
-----------
Mar 18 08:30:12 s01 vdr: [50364416] ERROR: frame larger than buffer (17392 > 8)
Mar 18 08:30:12 s01 vdr: [50364416] ERROR: frame larger than buffer (17514 > 8)
Mar 18 08:30:12 s01 vdr: [50364416] video cutting thread ended (pid=33513, tid=50364416)
Mar 18 08:30:13 s01 vdr: [50361344] info: Schnitt beendet

The cutting ends now always normally.
The cutted recording itself seems to be corrupted. When trying to
play it i got "incomplete PES packet":
-----------
Mar 18 08:23:05 s01 vdr: [54684672] receiver on device 1 thread ended (pid=33513, tid=54684672)
Mar 18 08:23:05 s01 vdr: [50363392] ERROR: incomplete PES packet!
Mar 18 08:23:11 s01 last message repeated 87971 times
-------------
until i stop playing the cutted video.
Same errors when doing it without a frontend/OSD from Terminal with
--edit and -i1.
