Denon 3808 Upscaling

I need to purchase a Blue/ray player hoping you guys can help me out.

IF I purchase the Oppo 83 it is known for its ability to upscale DVD's. Which is nice cause we still have a ton of regular Dvd's.

question: If I run the HDMI from the Oppo into my Denon 3808 will the Receiver try to upscale the video as it leaves the receiver and goes into my LCD? I was told only when the signal is 1080P will the Denon receiver not touch the signal from the DVD/Blue Ray Player? Is this correct?

I'm a bit of a newbie and need some help to make a smart purchase of my blue/ray player.


Thank you in advance!

Does it show how to do it in the manual? Have a hard time reading that thing. Any experience with the Oppo 83 vs lets say the Pioneer BDp-320 or the LG390? I do have a lot of regular DVD's.

Thanks

Since I'm currently using my Xbox 360 to play Dvd's and it is not doing any up-scaling, I believe my display is doing the up-scaling correct?

Again display is a Samsung ln55a950.

Does anyone know if the Oppo bdp-83 would do a better job at up-scaling then my LCd does? Or would the LG 390 do as good of a job as my LCD?

Thank you!
