Thanks for the tip on the digital OTA channels, I'll make sure to do that.

As for the 4DTV, it is a C-Band Satellite receiver and comes into Myth via
S-Video.  I have it only connected to the S-video input in Myth-Setup. 
Strange thing is that when I first created the line up, it did not find
most of the channels; I should have checked, but I bet it only found the
same 14 channels it wants to keep now.
 Until the present issue happened, I forgot how I got all the other
 channels in there before.  As many a mother will tell you, they forget
 the pain of childbirth once they see the baby.  That is kind-of where I
 was.  I had forgotten that I had hand entered some 100 channels via the
 channel editor.
On a side note, maybe someone with better skill than I could help create a
basic SQL script that I could populate and then run to fill the database
with this information.
Back to main story, after I entered the channels via Channel Editor,
mythfilldatabase worked great.  As I said above, I ran
¡§¡Xdo-channel-updates¡¨ and that is when things went wrong?  Looks like I
will need to re-hand enter the channels ƒ¼
