scanned channels and xmltv feed don't match up

I wonder if someone could suggest what might be going wrong with
my setup? Any suggestions would be very much appreciated.

I'm using the the latest version of MythTV from the
release-0-18-fixes branch and the RadioTimes XMLTV feed for the
UK with tv_grab_uk_rt from the Debian package of xmltv-util
version 0.5.40...

Essentially, the problem is that when mythfilldatabase runs for
the first time, it doesn't seem to add the xmltvid to the
exisiting channels that were found by the DVB-T cards on
scanning. Instead it creates new channels which aren't
associated with an mplexid. For example, immediately after
scanning for the first time, the channel list looks like this:

mysql> select chanid,channum,callsign,name,xmltvid,mplexid from channel order by (channum+0);
+--------+---------+----------------+----------------+---------+---------+

... and after running mythfilldatabase for the first time, it
looks like this:

Could anyone suggest why this is going wrong, and what the best
course of action is for fixing it? Apologies in advance in case
I'm just doing something stupid. :)

many thanks,

AFAIK, mythfilldatabase only populates the program listings when you're
using tv_grab_uk_rt.

What I did was edit the xmltvid field for each scanned DVB channel in
mythtv-setup. That should do the trick.

I really think it must have been mythfilldatabase that was
adding the channels; I hadn't run anything else between the
first database dump I quoted and the second...

Ah, thanks very much - I've done that and it seems to work fine
now. I also trimmed the *.xmltv file for my RadioTimes video
source so it only tries to grab the listings for channels I can
actually get, which seems to reduce the run time of
mythfilldatabase from 2 hours to 5 minutes :)

cheers,
mark
