[mythtv-users] Myth can't change channels on my dct2000

[Owen Mehegan]

OK, on a hunch I looked at the mythconverg database, and I figured  
out where Myth is getting these whacky channel numbers:

mysql> select channum,freqid from channel where channum +---------+--------+
| channum | freqid |
+---------+--------+
| 9       | 187250 |
+---------+--------+


So, when I tell Myth to change to channel 9, it feeds channel 187250  
to the channel changing app. Is something screwed up in my listings  
feed? I'm getting it from Data Direct/Zap2It or whatever, in San  
Francisco, CA. Or, is there some way I can tell Myth to use the  
channum column instead of the freqid column when I give it channels  
to change to? Not all of the channels are screwed up like this, but a  
whole lot of them are. If I tell Myth to change to a channel that is  
configured normally in the db, it is able to do so with no errors.  
I'm SO CLOSE!!
