I've been fooling around with the settings on my new Panasonic upconverting DVD player which is hooked up with an HDMI cable to my Olevia 532 LCD TV. I'm just curious which of the things listed above are the best.
I assume since my dvd player "upconverts" the data that 720p would be better than 1080i?? Any opinions on this? I'm driving myself crazy trying to find the visual differences... lol
As far as the 2nd part of the question... Which one of these color settings is best and what does the 4:4:4 and 4:2:2 mean?

Your picture starts out at 480 lines on the DVD. No amount of upconverting can improve on that resolution, but using a high-def format can reduce the degradation of the picture passing through amps and processing. It will not matter whether you use 720p or 1080i, since both exceed the DVD resolution. You should use whatever is the native resolution of your TV. If you have a 720p display, use 720p; if you have a 1080p display, use 1080i. Any differences will be slight anyway, and usually only visible on test patterns.
4:4:4 and 4:2:2 refer to the sampling rate of the components of the video signal. The first number refers to the number of samples used for the luminance (black-and-white component) of the picture, while the other two refer to the sampling rate of the color signals. 4:4:4 uses the same number of samples for all components; 4:2:2 means that the color components use half the sampling rate as the luminance. MPEG-2 specifies the 4:2:2 standard. The reasoning behind the limiting samples for color is that the eye has less resolution for color than for brightness alone. Reduced color bandwidth has been a part of color TV specs since the beginning.
Your color setting has to match the source, so use 4:4:4 only if the video source encodes the signal that way. DVD is 4:2:2 There is additional confursion here since technically Y,Cr,Cb refers to the video signal in digital form, while Y,Pr,Pb refers to the analog form. However, TV sets and sources use both designations for the analog form. If the signal is analog, it has already been decoded, and the sampling rate is no longer relevant.
