How do you turn a VHS into a DVD?

You need a DVD recorder. You can just connect the coaxial output of the VHS player to the coaxial input of the DVD recorder (with a short coaxial cable), but you might get better results if your VHS player and DVD recorder has the dedicated audio and video outputs/inputs. They will be RCA sockets, coded yellow for the video, and red and white for the right and left stereo audio channels. You can buy the coax cable and/or the dedicated cable at a Radio Shack store.
