a last questions: can the GET_STATUS ioctl disrupt the normal operation of the
frontend in any way? (there are a lot of ioctls when run the modified

Usually I had a problem with the _first_ vdr recording with triggers a driver(re)load and a vdr restart.
I use two rev 1.3 cards and therefore I made the old bsrv2 frontend driver compile with the actually dvb-kernel-driver (2.4).
I ran several tests and cold boots. Up to now I have no broken recording.
