What are the opinions regarding utilizing these 2 different inputs? Is YPrPb better because it allows you to adjust the color and tint?
Thanks

I take it this is for your D50?

Those adjustments are only needed for correcting Sonys analog component decoder conversion errors. 
I think RGB from source should be better for crt, because color space conversion is done in digital domain.

Component is used because that was the standard that the consumer industry decided to go with.

Just get the best picture you can get with the most contrast and shadowy details in black and white.... if you then decide to be one of them less retro guys, you can still watch 'em movies in pretty (accurate enough) colors. All though the color selection can have a bit to do with the color reproduction, usually it's all about tuning your apparatus.

Unless I'm missing something, why not take the non-compressed analog stream (ahem, RGB)?

Wan, component isn't necessarily any more "compressed" than is RGB. It's just a different color space.
There isn't actually a one-size-fits-all answer to this question. While your display my ultimately work in the RGB color space, the content you're watching was most likely stored in a component color space (and yes, compressed - chroma sub-sampled actually). So, where you do the conversion from component to RGB depends on which device does the conversion best. The only way to know that is to test. Use the one that gives you the most dynamic range and best color.
Dan, in your case, the D50 may take a component signal and convert just fine. Or, it may suck and you'd be better off converting to RGB with a Kim coder or running HDMI to an HD Fury and outputting RGB (that would probably be my recommendation). Unless something is amiss with your setup, or the source is deficient in some way, you shouldn't need the color/tint controls.

I am outputting hdmi to an HDFury2 out of which I can go either way. I am not that technical into what is involved with the various types of video outputs so I did not know what the differences if any there were between the two.
Thanks

Hmm, must be my listening to other folks. I thought the reason behind the CEA in developing Component video was to reduce the bandwidth necessary for transporting between device and imager. I was under the impression RGB was completely uncompressed, and that while green in Component retains its original luma and chroma information, red and blue did not.
My bad.
