Thanks for the info.  I have not tried using the Transports Editor, but
I'll give that a shot.  I select "Scan all known transports" and also check
the option to try new transports discovered during the scan.  I would say I
do have a partially working setup, insofar as I can find all of the other
HD channels just fine.  It's just this one which evades MythTV.

Thanks!
