Video upconversion
I had my coax cable going from the wall to my dvr, to my tv sets coax in. I decided to take the cable from the wall to the dvr, and run component cables to the Denon 3805 with upconversion, and from there to the tv via componenet. I was amazed at the picture. I'll be the first to say I'm impressed with upconversion. For a $100, with all the cable we watch, it was insane not to use that feature. I had no idea. I've had the Denon for 4 months and never took advantage of it. I had my DVD player going straight to the tv set with component cables, but rerouted them to the Denon for remote ease. I don't think there was a gain or loss in dvd quality there, but as far as cable goes, it's worth the price in gold.
