I can't find anything in the patch attached to #2418 that makes it 
important to which channel the eitscanner tunes. You enable listening 
on the special EIT PIDs unconditional.
We might find in the Premiere service information something that 
indicates if we should listen on these PIDs.
Otherwise a simple solution is to activate it based on the original 
network id (and transport id).

Not much different than now. EIT is independent of the channels.

I had first the impression that the PremiereEventInformationTable is 
basicly an EIT but it can hold additional descriptors. Do you have docs 
for the premiere private sections and descriptors?
