Hmm... I tried that... kinda, I set the zap2it ID in mythtv-setup, not the
frontend.  when I ran mythfilldatabase after the ID was set, nothing got
populated.  I got a question:

When you mapped your tuner to the local HDTV channels, did you push on the
"Retrieve Lineup from Source" (or something like that) button?  If so, did
you have to scan the OTA channels first (I think this is a new restriction
starting with 0.20)?
