Got a new gtv and with an hdmi hookup on my Samsung BluRay, the BluRay disks look great but standard DVDs look grainy (kind of like a VHS tape) which I hadn't noticed on the previous 32" tv in 720p mode. Same with much coming out of my FIOS Motorola hd DVR. Have option tod set output to 720p or 1080i, no 1080p option. This really makes standard DVDs look bad. Ideas?
