[mythtv-users] HDTV: channel num versus program id

I have been using a pcHDTV HD-2000 card with Myth for seven months. It
works extremely well.
A few months ago, my local WB & UPN stations gave up some of their
digital bandwidth to USDTV (an over-the-air "cable" company"). When
this happened, I suddenly could no longer tune in those channels using
my HD-2000 card.
This did not bug me too much since the TV season was over, but I decided
it was time to figure out why.
After waisting several hours, I discovered that while the official
digital channel numbers for these stations are:
19.1 WB
45.1 UPN
The actual "program ids" are:
19-2
45-2
Myth keys off of the "program ids", not the subchannel numbers. To fix
the problem, all I had to do was change the channel configs from 19-1
and 45-1, to 19-2 and 45-2. The only trick was figuring out that the
content I wanted was on the "-2" instead of "-1".
I was using a program by Peter Dicamillo to try and figure out the
problem, when I noticed that his program indicated that 19-1 was
actually program number 2.
If anyone is having trouble tuning a digital channel, try running
Peter's dtvstream program on that channel, and see what is says.

For example, here is the output when I ran "dtvstream -v -q" on my UPN
station (analog channel 50, digital channel 19):

ERROR in TS 0x1283 pkt Continuity Count - expected 11 got 2
