Question

I hooked up the new DVD/VCR unit and I cannot get any of the menu screens to show up. I called the manufactuer hot line and they verified I had done all the hook up correctly and I have power to the DVD/VCR player but they told me I need to swith my TV to Aux or game and I do not have those options on my remote control for the TV.
