I was thinking of getting the Denon 3803. I noticed it has video upconversion. I would assume it will pass a component signal as received straight through without change of any sort. My question comes in when it upconverts an S-video or composite signal to my Toshiba HDTV. I have a couple of stretch modes that I can use to make 4:3 material full screen. With my cable box, the signal it sends through component won't let me use any different stretch modes. I ASSUME the reason for this is because it is a HD cablebox sending a 16:9 picture with the 4:3 image inside of it with black bars on the sides to fill it up. In other words the black bars are actually being sent in addition to the 4:3 image. I guess when my TV sees a 16:9 source it won't allow stretch modes. I make this assumtion because I can use any stretch mode with any form of signal coming from two different dvd players(progressive/interlaced / 4:3 / 1.85:1 / 2.35:1 and any combination). Does anyone know if the video up conversion to component with the Denon 3803 may have a similar effect on my TV.
