I know how to use/hook up an RF modulator but, my Magnavox only has a yellow AV in and a yellow AV out on it as opposed to the red. yellow and white RCA's that hook into the Mod...any ideas on what I connect to the actual portable player? Using the portable as the only dvd player hooked up to tv w/out audio/video inputs..that's why the adapter (rf mod) Thanks SO much
