Yes, I did leave out the part about me going into mysql to set the mplexid
and serviceid. Unfortunately, I can't seem to get mythtv to pick up the channel's
program data without knowing the xmltvid and that's not something easily accessible.
That's probably the main obstacle to me doing everything from the mysql tables

Using the channel scanner is a bit cumbersome as I am using cable clear QAM
and the channel scanner picks up both encrypted and unencrypted subchannels.
Additionally, there's no PSIP data so the channel scanner doesn't seem
to be adding the new channels.

Yup, very destructive since Zap2it's channel numbers don't match the
channel numbers in my TV's tuner (because there's no PSIP data and I'm
not running cablecard).  However, it does have the advantage
of not requiring X (but I'm probably in the minority of the population that
tweaks the mysql tables directly anyway).
