I have had my Sony 36 xbr800 for about 8 months and never attempted to use the s-video imputs. The component imputs have worked without a hitch. Composite seems to work as well. I recently purchased Replay TV and attempted to connect it to the Sony via the s-video input 3. Same on input 1. The picture was highly distored, with fast moving horizontal lines. I then tried to hook up my Motorola DCT-5100 cable box via s-video and had the same problem. I replicated the problem with my Panasonic DVD player and Samsung over the air HDTV tuner. The problem is obviously the Sony, unless I am very unlucky with two separate s-video cables. Has anyone ever experienced this? Is there some method to enable the S-Video imputs on the Sony or are they automatically enabled? I checked the manual and did a search on this forum and could find nothing. Any help would be greatly appreciated.
