Spulciando un pò la rete ho trovato questo sito in cui si consigliano dei settings per la PS3 particolari e utili nella visione di film in formato BD, ma anche DVD

Cinema Conversion: Automatic
This setting affects how the player deals with film- and video-based standard-def material originating on DVD and Blu-ray. Automatic works well to differentiate between the two.
Upscale: Normal
This setting fills the screen properly when dealing with standard-def content converted to high-def by the PS3.
BD/DVD Video Output Format (HDMI): Automatic
This setting affects the color space output via the PS3. RGB is best for video games, which use the same color spce as computers, while Y Pb/Cb Pr/Cr is best for video, including DVD and Blu-ray discs. Auto usually works to detect the source properly, so we recommend most people stick with this setting. If you experience discoloration or other issues, try another setting.
BD 1080p 24Hz output (HDMI): Off
Most Blu-ray discs are encoded at 1080p/24 natively, which means they have 1,920 x 1,080 pixels per frame delivered at 24 frames per second, the native film rate. Many HDTVs cannot accept 1080p/24, however, and many more can but don't get any benefit from this setting, and can look choppy or otherwise incorrect. Unless your TV is designed to accept 1080p/24 signals--this includes most LCD models with 120Hz processing, as well as select plasmas with different refresh rates--you should leave this setting turned off. (Khurshid, for your 800U, we recommend choosing Off and ignoring Panasonic's 48Hz mode, which introduces unwelcome flicker). We also recommend avoiding Auto, because it can sometimes mistakenly output an incorrect format.
Display Settings menu:
Video Output Settings: [check all that apply]
This setting controls the resolution(s) output by the PS3. You should select all of the resolutions with which your TV is compatible. If you have a TV that can accept 1080p signals, you should select all of the check boxes. On HDTVs that cannot accept 1080p, you should check off every resolution except 1080p. The only exception is if you know your TV looks much better with 720p sources than 1080i. If that's the case, we recommend you leave 1080i unchecked as well.
Cross Color Reduction Filter: Off
This setting applies only to S-video and composite-video output, not HDMI.
RGB Full Range (HDMI): Limited
This setting controls the range of information output via HDMI. Contrary to what you might think, this setting is best left on Limited for video-based material like Blu-ray and DVD for the majority of HDMI televisions. Some newer HDTVs can receive a slight benefit from Full if calibrated properly, but in general Limited is the best choice, and we use it in the lab to ensure compatibility of the reference player with all displays.
Y Pb/Cb Pr/Cr Super-White (HDMI): On
This setting controls whether the PS3 will pass blacker-than-black and whiter-than-white parts of the video signal. It's really only useful during calibration, which is why we leave it turned on. Many discs don't contain material in above white or below black
Devo dire che su alcuni settings personalmente non sono per nulla d'accordo, ma la mia tv attuale non supporta nativamente i 24p..quindi posso solo starmene zitto e basta a riguardo
Sempre nella stessa pagina del sito ho trovato questo link a una pagina del forum americano avsforum.com (da non confonder con avforum.com che è inglese) in cui si danno altri chiarimenti a riguardo:
fonte: AVS Sony PS3 FAQ (PS3 used as a Blu-ray player) - AVS ForumUnder Video Output Format (HDMI), what are RGB, Y Pb/Cb Pr/Cr and Auto for?
RGB: A colorspace used by the PS3 to output video levels at a desired range. This colorspace is mostly designed for PC monitors. This is the desired colorspace for use in the PS3’s XMB interface and also for video games because they are encoded in sRGB.
Y Pb/Cb Pr/Cr: Another colorspace for use with displays that accept Y Pb/Cb Pr/Cr input. If your display supports it, this is the desired colorspace when watching DVD, Blu-rays or AVCHD videos.
Auto: Just like it sounds, it automatically selects between RGB or Y Pb/Cb Pr/Cr colorspaces depending on the source of the video. Selecting “Auto” will most likely result in the PS3 using RGB Levels for the XMB interface and Video Games, and Y Pb/Cb Pr/Cr for DVD and Blu-ray discs.
Which one should I choose?
That depends on your display, connection and calibration settings. Try using starting with “Auto” (see why above under “Auto” above).
I notice weird things happening with colors when selecting Y Pb/Cb Pr/Cr or Auto. What should I do?
Try forcing the PS3 to output RGB levels to see if this eliminates the problems. Your display may not accept, or may have trouble with Y Pb/Cb Pr/Cr input.
Does it matter if I'm using component cables?
TBD
So then under Display Settings, should I have RGB set to “Full” or “Limited”?
Most TVs can experience “black crush” when “Full” is selected because the colorspace is being mapped beyond what the TV is expecting. Start with it set at “Limited” and calibrate your TV accordingly. Use grey-scale test pattern images if necessary during calibration.
See this discussion for a more detailed discussion (for and against)
What about Y Pb/Cb Pr/Cr Super-White? “On” or “Off”?
Y Pb/Cb Pr/Cr Super-white is used to pass Blacker-than-Black (BTB) and Peak White (WTW) levels during video playback. Setting this to “On” should benefit your display as long as your TV accepts Y Pb/Cb Pr/Cr input over HDMI. Again, try using a test pattern DVD/BD to calibrate your display after this is turned on.
Not all displays are alike, so use common sense. If you notice a decrease in picture quality after changing any of the above settings either try recalibrating the TV or revert back to the previous setting.
How does the video compare to standalone players?
Most users think the PS3 is in the top tier of upconverting players, falling somewhat below only those with high quality dedicated chips like the Toshiba XA2.

How good is the DVD upconverting?
