DVD/Entertainment Unit Swap?

Thanks for the responses. We just brought the RV home last week and after a little investigation, it seems my task will be more difficult than I first thought. In someone's infinite wisdom at Keystone, they decided it to be a good idea to have the DVD only work on the main TV and not the one in the garage, the master, or outside. WTH!! Do they not think anyone would want to watch a movie on the TV outside? Or in the garage or master? So, I need to decide whether or not to go the easy route (get a Blu-ray for each of the TVs separately) or try to integrate them. I will more than likely just do it separately despite the cost just for the simplicity of it. This could have been such an easy thing for Keystone to do in the build process and would not have cost hardly anything. Sad.
