Yes looking to find how to hook up I have magnavox TV (cable) sony dvd slyvania vcr yamaha stero and rf modulator TY BILL

Hard to tell without knowing available Inputs/Outputs. Newer DVDs don't have Coax out, and older TV's only have Coax IN.
The Modulator converts Audio/video to be converted to Channel 3 or 4 (most of them) with a coax.
Look through here:
Monster Cable® Products, Makers of High-Definition Multimedia (HDMI) Cables, Video Cables, and Audio Cables for Home Theater.
Then Home Theater Connection Guide, then select cable and connection types. In color.
