I'm surprised that the bedroom and front end are different, though I'm certainly not an expert on digital over-the-air signals. In our rig, the antenna comes in at the front end, where there's a distribution box. Cable comes in at a connector in the electrical power bay.
You can hook VCR, DVD, antenna, cable and aux to the input side of the box and send whichever signal you want to watch to either to LR or BR TV. Since we don't have a TV in the bedroom at home, I took the one out of the RV bedroom.
Since the front TV is an analog set, I'm looking to pick up a cheap D-A converter. We never needed one at home since we can't get over-the-air signals because we're in an RF "black hole". We have to have cable. RF reception is so bad that, when I drove transit, I couldn't get through to base 20 miles away once I came off the hill down into our neighborhood.
We aren't big TV fans anyway, so even if we can't get it to work, it's no big deal.
