[mythtv-users] New York PBS WNET channel 13 pid mess

Wow....The New York PBS channel, WNET apparently moved and changed
their PIDs or something.  I first noticed this because an American
Masters show that was supposed to record was a a foreign language show
clearly from the wrong mult-cast.

I rescanned that transport (VHF frequency 13), which did change things
around.  However how I have a mess where the listings are using the
wrong channel ids.  Actually the listings are using the original
chanids that have now changed.  I've tried fetching the channel line
up as well which doesn't seem to have fixed anything.

Here are some key fields from the channel table before the rescan etc:

select chanid, channum, sourceid, callsign, xmltvid from channel where
channum like '13%';;
+--------+---------+----------+----------+---------+
| chanid | channum | sourceid | callsign | xmltvid |
+--------+---------+----------+----------+---------+
|   1131 | 13.1    |        1 | WNET-HD  | 26182   |
|   1132 | 13.2    |        1 | WNET-SD  | 31780   |
|   1133 | 13.3    |        1 | WNET-13  | 44667   |
+--------+---------+----------+----------+---------+

Here's what they updated to after the rescan:

select chanid, channum, sourceid, callsign, xmltvid from channel where
channum like '13%'

+--------+---------+----------+----------+---------+
| chanid | channum | sourceid | callsign | xmltvid |
+--------+---------+----------+----------+---------+
|   1132 | 13.1    |        1 | WNET-HD  | 31780   |
|   1133 | 13.2    |        1 | KIDS     | 44667   |
|   1131 | 13.3    |        1 | V-Me     | 26182   |
+--------+---------+----------+----------+---------+

You can see that they've switched things around in a really nasty
manner...no clue why.

When I tune to channum 13.1 in live tv now it does in fact tune to the
main WNET-HD multi-cast, which is good.  However the guide data from
Schedules Direct is still getting mapped to the old chanids.  For
scheduled program that should be on 13.1 still uses chanid 1131.

What does mythfilldatabase etc use to tie the listing data to the
channels?  If I remember correctly, I thought it was the xmltvid  If
that's the case, that would explain things, as they are still pointing
to the old channel table chanids.

As I mentioned, I tried fetching the channel line up and that changed
nothing.  Are the xmltvid fields the problem?  If so can I fix them,
even if it's manually in the database?

Quite the mess...

Thanks in advance.
Tom
