[mythtv] Edit Channel Listings

[Ryan A. Carris]

I was lazy when I ran the MythTV setup program.  I held down the 'enter' 
key for a few seconds while accepting channels.  Unfortunately, that 
caused it to accept all 999 channels (I didn't realize they would be in 
the listing since I did not select the digital cable listing).  Now, I'm 
doing a 'fillmythdatabase --manual'  and it is taking forever (over an 
hour w/ DSL).

My question, how do I edit the listings to get rid of the extra channels?
I've tried re-running the setup program, but it skips that step and all 
other steps such as my zip code.  I've tried hunting down the file, but 
I'm new to Linux and haven't had much luck.  

Thanks
