The runvdr script looks ok. Are you adding any further command line options when
calling it (especially '-d')?

Please make sure none of your patches messes up with the return level of
the main program (in vdr.c). In case of an emergency exit it has to return 1.
Here's how the end of vdr.c should look:

  if (cThread::EmergencyExit()) {
     esyslog("emergency exit!");
     return 1;
     }
  return 0;
