I connected a new Sony DVD player to an older Sharp tv. The tv has only a coaxial input so I connected the two via an RF modulator. The picture quality is good but the audio buzzes most of the time. The volume of the buzzing varries and changes when the camera angle does. I got a good quality coaxial cable and that helped a little but it is still pretty bad. Any suggestions to remedy this problem besides purchaseing a new TV? Thanks.
