I have just purchased a Thomson DSI 6210 Sky+ 160GB box from eBay. This is to replace my existing Pace box, which works perfectly, but has a much smaller hard disk. When I set up the Thomson box I immediately noticed that the picture jumps from side to side constantly, every few seconds, whenever the picture is displaying images with high contrast, e.g. the Sky+ menus. This only happens when I have the 'SCART Control' and 'RGB' picture settings enabled. I definitely want these settings enabled, as RGB provides much better picture quality than composite PAL. I have a fully wired, high quality SCART cable, and a Toshiba 42X3030DB LCD screen. These were both used with the Pace Sky+ box with no problems whatsoever. So... have I bought a duff Thomson box from eBay, or are they all like this? Is there any way to fix it, or should I send it back to where it came from?
