Our coach has two satellite connections outside, (1) for the living room TV and (1) for the bedroom TV, it also has a coax jumper that needs to be removed in order to switch the system from the cable to satellite.
Now that's something I never considered. My unit has two unmarked external antenna hookups, I just assumed one was for cable and one for satellite. Duh.
I never worried about it 'cuz I've only ever twice cranked up the roof top antenna (first time a test, second time my bride wanted to watch fat people racing around the world) and it worked.
I've also never tried the built in DVD (BluRay?) player.
