I have a Mitsubishi big screen tv dish network-Tivo 522 vcr-samsung and Dvr-Mustek, when Dish installed they unhooked everything and then supposedly hooked it all back up but can't watch vcr and can't record vhs to dvr . Can some one help. My TV has: Cable in plus two outs, also video hook ups and dvd hook up but the satelite guys couldn't figure it out and they messed with it for an hour can anyone help me.
