I have an update on this, if anyone cares to know.  I have approximately 
328 channels in my SD lineup, which include several Music Choice music 
channels and premium channels that I don't subscribe to (HBO, Starz, 
etc., and their associated bundle channels).  When I do a scan via 
MythTV, I get 278 unknowns (UNKNOWN17#0, etc.) and 50 known.  I have 
gone thru every single channel and have only identified 50 that are with 
my lineup.  The other 278 only show a blank screen.  A few of them gave 
me the "you should have gotten a lock by now" message, but a vast 
majority of them seem to lock on to the channel, but show no TV data at 
all.

50 out of 328 seems awfully low to me.  Many of the channels that I get 
I don't care about, and the ones that I do care about (USA, FX, etc.) do 
not seem to be tunable.  I have a web page I made that shows my SD 
lineup (made from an original spreadsheet with 2 sheets on it; 1 with my 
SD lineup and what I have for channels in Myth and the other a list of 
the unknowns) with the known channels highlighted green, the not-tunable 
channels as red, and the premium channels in orange. It is located at: 
http://www.ourapplecart.com/sd.html .

I am attatching the output of a dtvscan run that I did.  It lists QAM 
channel frequencies, but I'm not sure what it's showing me and whether 
or not this can help.

Thanks,
Harry
