Ah, it's http://www.mythtv.org/wiki/Frontend_Channel_Editor (wiki got 
rearranges and the index.php shouldn't be in URI's, anymore).

Right.  That's the approach you want to use.

Your cable operator is sending garbage for your channel 
information--most likely it's out-of-band information in the form of 
SCTE65 data--so, since Myth doesn't find any useful information in the 
stream, it makes stuff up.

If you're using Comcast (or another provider using SCTE65, see 
http://www.mythtv.org/wiki/Comcast_Users_And_scte65scan (which will 
solve all your problems).
