Interesting . . .
I've tried to get our cats to help us out with this, but all they want to watch is Animal Planet!
Since most of our camping is done in or near the mountains (right now all flooded out by all of the rain we've had this week), we rarely can pull in any TV stations, so rely on the BluRay player for our watching.
We have Direct TV at home, but don't have the setup to use in our camper.
One thing I have discovered when programming the channels on our two TV's in our trailer is that once I program one of the TV's, I have to turn the other one off or they won't pick up the channels if both sets are on.
The other interesting thing . . . if the TV next to the built-in Jensen AM/FM/CD/DVD player, it blocks out the radio reception!
Hhhmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm . . . . . . .
