Source called 4DTV. (In the U.S., a 4DTV is a satellite receiver.)

Again using the Backend Setup, under Input Connections I associated 4DTV
with the "Composite 0" entry.

Again using Backend Setup, I entered the Channel Editor and defined a new
channel. It is easy to miss filling in all the blanks on the screen here. I
filled in the Video Source as 4DTV. Arbitrarily, I filled in Channel Name as
W4DTV, and filled in the Call Sign as WSAT.

Now, the 4DTV Satellite Receiver is defined to MythTV as Channel WSAT.
There are no program listings for it in my system, so I use Manual Recording
to first select the Channel called WSAT, then set the Start
Time/Date/Length, etc.
The 4DTV Satellite Receiver has a VCR-like programability, so it is not too
difficult to set both MythTV and the 4DTV to turn on at the same time, tune
their respective channels, and end up with recorded program(s) from the
satellite dish.

To some, all of the above might sound complicated, but the MythTV system
just took the place of several VCRs that were also programmed to record from
the satellite dish by coordinating the start-stop times of the receiver and
