I just upgraded to directv hd today. I have a 37''LG LCD display with a top setting of 1080i and i have a few questions. I will be hooking my reciever to my hd set via an hdmi cable. Will the reciever upscale SD channels to HD and display SD channels in 16:9? Right now with an SD reciever and composite cables the channels look blurry and grainy with a black bar on the left and right sides of the screen. Can anyone answer my questions? Thanks
