PS3 Settings for Blu-ray?

[Gung_ho]

Hello again,

Now that I've resolved my tv callibrations for my LN46A530 Samsung , I was wondering if I can get some input on my PS3 settings. I've done some searches but only found partial settings...(e.g. use YPb/cBPr/CR, RGB set to limited, Superwhite enabled), which were helpful but haven't seen suggestions for other settings on the Video settings.

What do people normally set the following at for best Blu-ray movie viewing?
BD/DVD conversion - audio or video?
DVD wide display - letterbox or pan and scan?
BD/DVD upscaler
BD 1080p 24 Hz - auto?
BD/DVD audio output format - linear PCM?
BD/DVD audio - bitstream??

ps. I'm directly hooked up to my TV via HDMI cable and I've got my Video Output settings set to 1080p

pps. one more question - on my tv, when I turn on my PS3 it'll say 1080i and when I put in a blu-ray it says 1080 (no "i" but also no "p" either) - shoud there be a "p" after the 1080??

Thanks in advance!
