Correct.

Yes, yes...

After exiting "setup" but before(!) you run mythfilldatabase,
edit $HOME/.mythtv/<sourcename>.xmltv . Put "#" in front of
the channels you don't want to include. The grabber needs to
verify that the channum and callsign are there but won't grab
data if it is commented out.

If you have two sources and they both have a channel 7, there
would be listing for 1007 (coax input) and 2007 (set top box).
If you picked a show to record on the EPG, it would only ever
record on the input of the listing you happened to pick. Avoid
this =).

This is easy! Don't setup an IR blaster ;-).

MythTV will tell the card which input to use along with all
the other info for recording parameters that you set through
the user interface.
