I once had a SD/HD mixed system.  its currently all HD... but..

I set up the system before qam scanning was working correctly...  I
set up zap2it to for a source of the channles I got free over the
cable.... once I ran mythfilldatabase, I went in and populated the
freq, mplexid, etc...  (this process is a little fuzzy in my head
though)

As an example..  ABC

analog scan 6 = ABC
HDTV  601, 602, and 603 = ABC and the affiliate's sub stations...
(channel numbers from zap2it)


I typically only used Mythweb for scheduling...(it has the handy HD
identifier in the listings)

If I look at my listings, I'd have a 6 and a 601, if I select it to
record on 6, it records on the analog capture.. if I select 601 it
will record of HD.

Also if I do a serch, It will come up with 2 hits showing the program
on 6 and 601.  I can select to record it in HD or sd.
