According to "ETR 162", Network ID 0x0000 is not assigned to any
real network, and is marked as "reserved".

Since VDR needs to be able to identify channels by their transponder
if it doesn't know the NID/TID yet, I suggest checking for both NID _and_
TID being 0, as in

tChannelID cChannel::GetChannelID(void) const
{
  return tChannelID(source, nid, (nid || tid) ? tid : Transponder(), sid, rid);
}

Or is there also a TID with 0 value?
Nevertheless, the real problem seems to be that the tv station uses
a bogus NID...

Please send it to me asap, I'm currently in the mood to do this ;-)
