I put a DVD player up front in the cabinet with the selector box and connected the cable to the satellite input. When the selector switch is in that position any TV in the MH that is set to antenna and turned to channel 3 plays whatever is in the DVD.
I also leave an HDMi cable connected to the bedroom TV routed to the closet on the left that I plug a bluray player into on occasion if we want to use that. If you remove the small screwed in panel at the top of the closet you will find the AC outlet for the TV that you can plug a DVD or Bluray player into.
