OK, I just started trying to map the HDHomerun lineup frequencies (I
don't have an HDHomerun; only a pcHDTV-5500 card, but their lineup for
my zipcode is the only source that I've seen where I can see the
relationship between the transmitted channel and call-sign) to the
channel names/numbers that I'm familiar with, and I want to be sure I'm
going about it correctly. I am using the channel editor via MythWeb.

The HDHomerun lineup (via the link above in my original post) shows the
following for those channels (I assume):
qam256 113 1 WPVIDT 1280x720p
16:9
<http://img.lineupui.silicondust.com/snapshots/snapshot_21995.jpg>
qam256 113 2 WCAUDT 1920x1080i
16:9
<http://img.lineupui.silicondust.com/snapshots/snapshot_20777.jpg>
qam256 113 3 WPVIDT2 704x480i
4:3
qam256 113 4 WPVIDT3 704x480i
4:3
qam256 113 5 WCAUDT2 640x480i
640x480p
4:3
Do I have to do anything with the finetune column? I just want to make
sure that what I'm assuming is correct. Also, the HDHomerun lineup
shows alot of 8VSB channels, but when I scan for channels in Myth, I
don't get any of these. Only these digital, unencrypted ones (like
79#0, etc.).
Thanks alot for all of the help.
Harry
