I have a Toshiba sd900 connected to t.v via scart-scart lead. For scart-scart connection there are 3 options: RGB or s-video or composite. RGB is supposed to be best but with my sd900 the picture is darker and not so sharp. In s-video mode the picture is noticeably brighter and sharper, infact maybe too sharp. Do others have the same issue with the toshiba sd900?
