Ok heres the Deal.. I have an EDTV with 811 receiver and I'm wondering is it best to set the Receiver at 1080i or 480p. Cause I know my TV accepts 1080i but if I am correct an EDTV just scales down... so basically i'm just wondering how I should setup my 811. Right now I've had it at 1080i and I have all my SD channels stretched. Hooked to Plasma with Monster M500DVi Cable.. Any help?? thanks
