Well, all current DVD movies are at 540 lines of res. right? So your DVD changer is upscaling to 720p then the TV is upscaling again to 1080p? That is two upscaling passes. I just recently did a bit of toying with my 6168 and my Panny S97 DVD player. I found that bar none (surprise) the 1080i output of the DVD yielded the best picture. Tweaking the AV Enhance settings on the DVD pretty much eliminates the majority of macroblocking, at least in tmy test materials.
I would say all the comments I have seen are correct regarding decreasing processing when possible. The fewer upscaling passes the better. I would output at 1080i and call it good.
Works for me at least. YMMV
