Thanks for the reply, Bill.

I've been all through mythtv-setup and I don't see any 'quick tune' check box. 
Again, I'm using Axel's ATRPMS main packages -- mythtv-0.20.1-157.

I see his mythtv-trunk tree, which seems to be 0.21-159. Do I need this? If 
so, does anyone know of any issues upgrading between the two?

Other than the missing channels, the scanning tool seems to do a pretty good 
job. I just wish Astound Cable would put some identifying info with the 
channels. I've got some perl scripts which cross-index the frequency and 
service ID and insert the channel number, name, call sign and XMLTVID.

Bummer. I thought that would be nice to have. No matter. We mostly listen to 
our MP3s through MythMusic anyway.
