If you look back through the list archives you will see we all have the
same problem. Imparja doesn't advertise a SID, and MythTV requires a SID
to lock the channel.

Basically it looks up the SID, and then uses the PMT table to find the A/V
PIDS for the channel. You can't currently hardcode the A/V Pids.

There was some discussion on the main MythTV mailing list about a way to
implement Imparja support, but none of us have had enough time to
implement it.
