[mythtv-users] Digital channel ordering

I was lucky to have tone of digital channels on my cable (QAM) when I moved
so I got the HDHomeRun recently to complement the pvr500 I already had in
the system. For the last couple of days I was going through the ordeal of
mapping channels to their real numbers/names.

Back when I had hd2000 I remember digital channels showing up correctly in
FE. Like, 4 WNBC comes before 4.1 WNBCHD etc. Now I have channels sorted
seemingly in random order. The SD channels are sorted fine, but digital
channels are all over the place. I triple checked my ordering preferences
and for the life of me I can't figure out what logic FE is using to sort the
channels. I tried numbering digital channels like 4.1 and 4#1.

The only thing that worked properly was giving digital channel the same
number but different call letters, i.e. 4 WNBC, 4 WNBCHD and different
xmltvid. Then they showed up together. Is there any problem with having
different channels have the same channum? Is there any other way of doing
this? To make things worse Mythweb is behaving differently and using this
scheme makes digital channels disappear in the listing (they are still there
in the channel lineup). I guess Mythweb only uses channel numbers and since
there are duplicates, it removes the new channels.

Is the problem coming from the fact that channum in the db is varchar and
not a number, so 'order by' doesn't work as expected

Overall, I have to say that I'm pretty impressed with HDHR so far. The only
glitch is that most of the time watching live HD program is not possible due
to hickups and lag. Oddly enough watching same program on my laptop in vnc
over wifi works better!? I guess there is no disk r/w involved. But recorded
show play beautifully with no problems so far (cross my fingers).

Thanks for any insight.
