The cable arrived and I installed it. I now get the full screen, but the box is only recording in 480i, including the HD broadcasts. When I was using the 8000HD and component cables, I found that I got a better picture on SD material by using the S-video output on the box and the S-video input on the samsung. When I hooked up the 8300HD, I used the same cable setup. I left the S-Video connection when I substituted the HDMI/DVI cable and the aspect problem was resolved, but I now have this recording resolution problem. I've disconnected the S-Video cable, so that the only output connection I now have is the HDMI cable to see if this resolves the problem. Of course, the little brochure TW provides with both the 8000HD and the 8300HD explains nothing beyond very basic data. The on-line manuals on the SA site have more information, but nothing covering my problem. However, the SA site does not say to hook up a S-Video connection in conjunction with the HDMI connection; so, the advice given in other parts of this Forum to use the S-Video connection rather than the component for SD may not apply when an HDMI connection is available. Time will tell.
