I am assuming that the sole purpose of an upconverting DVD player is to display the DVD at original 16:9 ratio in its full 852x480 resolution (that is if the DVD actually contains 852x480 resolution(lots of DVDs are 4:3 ratio with 720x480 standard resolution).

But heres the thing, as far as I know, in order for something to be HD, it needs to be at least 1280×720 resolution. Therefore if someone says a upconverting DVD player converts DVD to HD then they are lying. -source for minimum HD requirments(http://en.wikipedia.org/wiki/High-definition_television(see "Digital Video Resolutions"(ctrl f)))

What are your thoughts?
