[mythtv] DVB - "Unable to find channel in database"

[Blammo]

I've run into a situation (can't figure out how) where a null value
gets entered into the startup / pretune value on the DVB card. I can
change it in SQL, and it changes itself back to null.

When you head for LiveTV, it fails to change the channel, and you're stuck.

Which gives you this:

The channels DB is full of working channels.. Been working fine for a while.

This doesn't strike me as the right way{tm}.
