Need some help from the video experts here. I have a small TV that I want to use to navigate DVD-Audio menus. It only has a coaxial input jack on the back and I am not sure how to adapt it to the "RCA style" video output on the back of my Oppo 980H player. Do I need a special adapter? I tried a plain ole F connector to RCA plug adapter from Radio Shack but the video is scrambled. I assume this is because there needs to be some conversion to get it in coax form? Advice? Suggestion? Thanks.
