Advertisements My first post here, I think. I bought a used TCD648250B with lifetime sub on eBay. I use OTA antenna input, then out to a nice Sony SD TV that has both S-video and Component video available. I hooked up the Tivo and started setup and almost immediately said "uh-oh." The picture has what I would describe as a background, diagonal wavy effect to it. I mean, the image is essentially fairly strong and stable, lines straight, text readable, etc., but the constant wavy effect is not tolerable. I had hoped that after completing setup and going to live TV the effect would go away, but it did not. I tried both S-video and the Component output, but it made no difference. With my digital converter box, using S-video, the picture is superb--crisp and natural, actually better than the Tivo, discounting the wavy effect. Any input would appreciated. (Other than, why do I still have a SD TV. Easy. Superb picture and I'm happy with it.) Thanks in advance!
