If you watch a DVD from the player (for example the OPPO), the OPPO resizes 480 x 720 into 1080 x 1920, and the overscan does what I wrote above.

By the way if you have an OPPO and like Scope 2.35- 2.40 movies with less bars, you could also turn overscan off on the TV(engage 1:1) and then use the Oppo 1.2 zoom and Scope movies end up being about 2.00, near to 1.85 movies.
I was merely explaining to Chip that I had read this following statement from member Aramis here, who said this some time ago (but I suppose, based on Chip's comments and now yours, that he was wrong):

Overscan doesn't mean you're not getting 1:1 pixel matching. It just means that some of the image is hidden by the bezel.

I still prefer DVDs and Blu-rays with some overscan; can't really explain it save for the fact that I'm not really at an ideal seating distance from my display and it makes scope films, at least, "feel" bigger. At any rate, it's better than zooming the 2.35:1 or 2.40:1 image to ELIMINATE the letterboxing altogether, as that would DEFINITELY introduce distortion and loss of resolution...wouldn't it?

As for where I'd want the overscan to be applied, I'd rather just let the display handle this so I don't have to switch this setting on a disc-by-disc basis.
