 I'm running 9488 and am seeing a segfault on the frontend whenever I tune
 to a DVB radio channel. I'm not in the UK so I don't know if there are any
 MHEG streams but it looks like the backend is recording a new stream which
 may be MHEG related?

 From the backend:

 2006-03-24 16:10:12.234 DVBRec(0): SetOutputPMT()
 Program Map Table ver(1) pid(0x21) pnum(1) len(34)

  Stream #0 pid(0x100e) type(audio-mp2-layer[1,2,3]  0x4)
   ISO-639 Language: code(eng) canonical(eng) eng(English)
  Stream #1 pid(0x1a0e) type(private-sec  0x5)
  Stream #2 pid(0x21) type(video-mpeg2  0x2)

 From the frontend:
