Denon AVRs and upconverting DVDs

[Dean]

I have an older 300 disc DVD player from Sony. It has component video out. I am getting ready to purchase a Denon AVR and a Panasonic Plasma 1080p 42" HDTV. Was wondering if I use an HDMI cable from the AVR to the TV, and if I hook up the DVD player to the AVR via component video cables, will the AVR upconvert my DVDs to 1080p? Will the Panasonic Plasma set do it?

I was considering the AVR-590, but was not sure if it will do upconverting of video. Does the 790 do this? I would buy the 790 (for about $150 more) if I knew it would do this upconversion, otherwise I'm fine with the 5.1 over 7.1. Does anyone know if either of these AVRs will do this upconversion? If they won't, does anyone know what my best solution would be for this issue?

Thanks.

BTW... wonderful forum!
