Shopuld I upsclae to 1080P at every stage or only once ?
My Blu ray player upscales to 1080P - My Denon AVR2808 Amp Upscales to 1080P and my Philips 46PFL9705 LED TV upscales to 1080P. Should I only upscale once ? or does it make no difference. If I should do it once, at which stage should this be done ?
