i've got my macbook pro hooked into my receiver, which is then hooked into my vcr/dvd combo, which then hooks into my coax input of my tv. (its an OLD tv). what i'd like to do is set it up to display video full screen on the tv, so i can play around on the laptop. it works great when mirroring, i have no problems with that, but sometimes i'd like to put a video on fullscreen and have the tv going with a movie or somesuch. does anyone have any knowledge as to how to do this?
