Hi Asa
Personally, I would set ANY current Bluray Player (Sony PS3, Sony BDP, Pioneer, Oppo, Denon etc.) to output the NATIVE Content of the vast majority of Bluray Discs, i.e. 1080p/24

My rationale being that the Native Content of Bluray at 1080p/24fps is a long way forward of DVD's 576i / 480i Content and thus any Video Processing will only lead to visible issues. Better to let the Native (good quality) content get all the way to the Display (or possible a Video Processor)

As most Displays can now handle 24fps, I see no advantage to outputting at 50 or 60Hz, as the Player then needs to perform Processing, which may lead to undesirable artifacts. I would say that the only reason to output 50 or 60Hz is if your display does not support 24fps.

Likewise, I would turn off all Video Processing features (including those on the Pioneer and Denon)

I would do the above whether sending the 24fps Signal straight to a 1080 Display or to a Video Processor

Maybe others can comment on what the newer Lumagens can do for 1080p/24 material, but I suspect not a great deal

Hope that helps
