In Reply to: Video Up-conversion posted by jbc on March 20, 2003 at 10:43:42:
As you know, the Denon 3803 (and some other models) have a feature that takes various video input sources from composite video VCR's or S-video, etc. and "upconverts" the signal out to it's component video output. This allows for running just one set of component video cables from the Denon to the TV as all the video signals come through that connection.I haven't really compared the video "upconversion" picture quality vs running S-video or composite video direct to the TV. I just recently placed a VCR in the setup so I might experiment with that. Running just one set of component video cables to the TV is a real convenience but I'm not sure if this "upconversion" actually helps picture quality from the other sources (like VCR composite video or S-Video).
Follow Ups:
If you ever do decide to play with your composite/S-video cables please let us know. I'll admit, in your position, I probably wouldn't bother.I suspect the upconversion feature is largely a convenience issue for composite/S-video hook-ups. Whether or not it's detrimental to component outputs (HDTV/DVD) is probably debatable... and would also be useful information.
I would connect the DVD directly with a better cable, leave everything else thru the receiver, but try if you can see any differences...

Good point... If the receiver is doing some magic "upconversion" to the various video inputs, I wonder if it is simply feeding the DVD component signal through or "processing" it too, possibly causing some harm to the picture quality. I'll run the DVD direct to the TV and see what happens.
