I finally got some time to try updating the channel settings..

The non-PSIP channel had a NULL entry from atscsrcid,  and I changed
sistandard from atsc to dvb (it was set to atsc from channel scans
done with previous versions of MythTV).

Unfortunately, I was still not able to view the channel (ESPN-HD).

Also,  one possible issue with changing atsc -> dvb:  each QAM channel
contains two full "channels" of data.  For example, channel 116 on my
cable system has KNTV-HD, KNTV-W (a low bandwidth SD weather channel),
and ESPN-HD.    KNTV is an atsc channel, with full PSIP data, ESPN-HD
does not.    Since the entries in dtv_multiplex deal with QAM
channels, and not individual programs, this creates a conflict.

I see, in that ticket, that the channel scanning has been changed to
pick up channels without PSIP data.    I grabbed the latest svn
snapshot, and tried it out.

The QAM channel scanning is MUCH faster.   It whizzes through those 80
analog channels..  this is very nice.

It recognized many more channels now, and it gave many of them
seemingly random channel numbers.  For example, it added 9152-1
through 9152-11, 8113-18, 93-1 through 93-9, and others.

On QAM channel 116 (with mixed PSIP and non-PSIP HD channels) it
didn't recognize either of the channels.
