[mythtv-users] Possible to manually add QAM channel information?

I posted a bit of information on this in the pchdtv.com forum: 

Basically, there are two tables you need to be concerned with,
"channel" and "dtv_multiplex".  Channel has the basic channel mapping
info, with xmltvid, and refers to an entry in dtv_multiplex.  The
dtv_multiplex entry has the actual channel frequency.

I modified the channel configuration in mythweb to allow editing of
the relevant channel fields.  I will try to create a patch for that
tonight, so you can use that if you want.    That would still not
address the entry in the dtv_multiplex table, which is normally
created when doing the channel scan.

I am able to watch QAM HDTV from my cable provider using a combination of dvb-apps, dvbtraffic and mplayer but scanning for the channels using the latest MythTV cvs doesn't seem to work, i.e. it doesn't detect the channels on the first pass and gets "stuck" on subsequent scanning of existing transports.  My understanding from the few scant threads I've been able to find on the subject seem to indicate that my cable provider is not transmitting certain information that Myth requires.  I have tried calling them and speaking to the engineers but have not been able to make much headway through the red tape, though my limited knowledge on what exactly is missing probably doesn't help either.

I am certainly no expert with MySQL but I think I could figure  out the relevant commands if someone could point me in the direction of the relevant table(s) that I would need to modify.  But of course if someone knows the actual command that would be very much appreciated as well.  Or is there perhaps an even easier way than modifying MySQL directly?  Or should I not waste my time trying, i.e. a fix is imminent?
