Well, it's very simple:

- locate the file that contains the error message:

  kls@hawk2:/home/kls/vdr/VDR > grep "nknown picture ty" *.c
  remux.c:                           esyslog("ERROR: unknown picture type '%d'", pt);

- edit that file and change the lines

                        if (pt < I_FRAME || B_FRAME < pt)
                           esyslog("ERROR: unknown picture type '%d'", pt);

  to

                        if (pt < I_FRAME || B_FRAME < pt) {
                           esyslog("ERROR: unknown picture type '%d'", pt);
                           cThread::EmergencyExit(true);
                           }
