Yes, AUTO upconverts but also puts through native resolution. It really depends on how you want it to handle and display things.
I'm at work tonight, so I can't re-test but I'm pretty sure THROUGH gave me upconversion and DIRECT did not. Anyway, now that you know how it works, you can run through the various options and see what works best for you with any given input.
I do like the PQ with upconversion for the 480i signals on my DCT6416iii and was leaving it on AUTO, however, some times I would prefer to watch some of these in 4:3 expanded mode (which my Panny plasma calls JUST), instead of 4:3 or 16:9 (FULL) and using DIRECT allows that.
It's a little confusing to me too still as you can control your video adjusts both with the 609 and your TV and their interactions.
