I've said it before, and I'll repeat it: it's the broadcasters' fault!
The PIDs must be set correctly _before_ a broadcast starts!

Of course you could change cChannel::SetPids() so that it doesn't set
the CHANNELMOD_PIDS flag in case only the language codes are changed.
However, this won't help in case of a change in PIDs during a broadcast,
but then again this is a sign of bad broadcaster quality, and that they don't
care about their viewers.
