My toshiba tv has a hdmi hookup, my 811 hd dish satellite receiver has only dvi out put , would i gain anything buy going with a cable with hdmi on one end and dvi on the other end, vs the way i have it hooked up now with component cables . the component cables im useing are the ones that came with the satellite receiver. or would i be better off upgrading the component cables with some 70 or 80 dollar rat shack stuff. thank
