Did you create a new video source for the cable box channels? Is it attached
to the correct input/card?

Did you make sure that all channels on the cable box's source have got the
correct 'frequencies' for the channel chager script to use?

Yes, I made a new video source and a new lineup on schedulesdirect.org too.
Took a few mythfilldatabase runs to get the guide data in. Also, Since the
cable box uses the rca input (composite connection), how would I know what
frequencies to put in? The channel changer script works great when I'm
viewing the cable box input (input 1).

In the area in mythtv-setup, you can put in an external changer command...i
did this, but only for the video input that the cable box is connected to
(input 1). I thought that when watching the other video sources (inputs
2-4), they would not run that command since it was only filled in for that
other video source. That is the part that is confusing me. How did the other
inputs 2-4 get mocked up when I put a changer script only for input 1.

Any ideas?
