Mabey you guys can correct my whole understanding of this upconversion.
My guess is you would only need to upconvert through your receiver if your DVD player is older and only supports composite or S-Video. Now depending on your TV's native resolution it would be useless to upconvert to 720p or 1080i if you TV only displays 480.
My Toshiba Plasma has a true HD picture at 720p, my Denon 3910 can upconvert to 720p or 1080, should I leave the DVD player at 720p, I'm thinking if I put it at 1080 the TV will just downconvert it back to 720 which will probably degrade the picture overall. the same goes for my Xbox-360.
This is just my understanding, please correct me if I'm wrong.

Upconvert changes composite to s-video to component/hdmi/dvi depending on pre/pro or receiver.

Upscaling changes resolution from 480i to 480p or 720p or 1080i or 1080p. This is done in newer tvs and newest receivers.

The only problem with no connection from receiver to tv is no onscreen display. Little lines on the pre/pro is all you get. Some have corrected this problem by adding a small tv to get a pre/pro feed.

Typically people upconvert composite or s-video connections on an AVR to allow those older sources to input to TV at HDMI/DVI.

Upscaling is typically used to convert older 480i/480p sources to a 1080i/1080p capable TV.

Most current HD TVs will upscale internally all sources to it's highest output anyhow.

Granted, I could be completely wrong here but this is what I've learned over the past year or so.

Michael, as the other replies have indicated, different types of so-called "converting" should be kept separate. Transcoding in a receiver allows composite and/or S-video inputs to be put into a form where they can all be output from the receiver's component output cables, instead of having to use different types of output cables. This doesn't make the composite or S-video input equal in quality to a component video input, it just makes it convenient to use just the component cables.

The scaling and deinterlacing of 480i material(DVDs, SDTV)to fit your 720p TV has to be done by the set itself if it hasn't been done earlier by a player, receiver or a separate unit. What's best depends on which of these does the best deinterlacing from i to p, or scaling from 480 to 720. You're right, there'd be no purpose in setting your player to 1080, since the TV would have to scale it back down to 720. You should experiment to see if setting the player at 480i or 480p instead of 720p would give you a better picture. This would have the TV rather than the player doing the deinterlacing and/or scaling.

That's a great idea, I'll try that to see if I notice any difference.

Make sure you do a double blind test! you want those results to be accurate!

Bug: just connect your receiver's video output to a different TV input. That is the way I can get on screen menus from the receiver to the TV. I use an S-Video input because high resolution is not an issue.

My Sony has a total of 8 video inputs. Four HDMI/DVI and/ or component inputs should be enough for most people. If you (reference the 50 video) really need more than 6-8 inputs, maybe you should get a video switcher.

My OPPO will send a 720P video signal. I have tried it both with the 720P and the 480P. I don't see any difference, but that is just me.

I couldn't really notice any difference switching between 480,720 and 1080, but again my eyesight is not as sharp as it was when I was younger.

I think that everything washes out when my Sony converts from whatever to 1080P.
