Built-In Upscaler for Playing HD Video
The AVR-1913 is equipped with a video upscaler that converts standard-definition analog video into high-definition 1080p signals. As a result, you can enjoy standard-definition video sources in the detailed quality of high-definition.
Wow! Who knew! A true miracle in video engineering! Soon I will be able to blow up my cell phone images to rival that of high end Canon and Nikon DSLRs.
On a more serious plane, I am thinking of getting a Denon, and Link to sales blurb gives specifics of a 7.1 model, refurbished, that seems much more current than the 5.1 model, linked on the left side of that page.
I really don't need or want 7.1; 5.1 is more than enough for my needs.
Any thoughts on the relative merits of these two?
