I can confirm these messages for Berlin. I assume vdr gets this
information from NIT (pid 0x10)? then again the broadcaster is doing
something weird? Or is vdr using the get_frontend-ioctl?
The flipping field is CoderateL, which afaik not in use anywhere in the
world?! So normally it should be FEC_NONE as long as hierarchy is turned
off. Maybe vdr should manually take care on that?
