Just got my mitsubishi 62725, and am hooked up to dish network with 811 HD reviever connected with dvi-hdmi cable. Put the picture in 1080i, and now sometimes have red or green pixels at right edge of picture? Any ideas on what is causing that? Also, when I put it in 1080i the picture size closes down on sd pictures. Do I have to change it back down to 480p for sd? or is there something else I can do. Thanks a bunch for the input!
