I can't help with the color matrix setting but as far as Cb,Cr it is another name for Component video. At this site under glossary-component, it states "These components are referred to as luma and chroma and are defined as Y'Pb'Pr' for analog component and Y'Cb'Cr' for digital component.
If you connect the Y Pr Pb ouput from DVD player to LT150, then you should set the colour matrix of LT150 to be Y Pr Pb. There are Pr/Pb and Cr/Cb out at my Philips Q50 DVD player. Pr/Pb is the proressive scan component out while Cr/Cb is the 480i component out.
Still some questions, of course. I haven't gone back to check, but I think the LT150 gives the option of either "HDTV" or "SDTV" but 480p would seem (by virtue of the informative reference from Sonogr4) to be "EDTV" or some such thing. So which to choose???
I guess it's time for plug and play... i.e., I play with the settings...
I've spent some time with Avia on my Lt-150 and by my estimate (using the 'Color Decoder Check' frame and the various filters) the Cb/Cr is a more accurate color setting to my eyes. There is less red push, somewhere between +5% and +10% by my estimation, and green shows not quite +5%. Blue is spot on after going through the 'Blue Color Bars' test.
When setting my LT-150 to Pb/Pr, the red push is noticeably greater and the green check is somewhat higher as well (closer to +10%).
Having said this, I've never been very comfortable with the accuracy of the red and green filters supplied with Avia ... so who knows. Milori... if you are reading this ...when can us LT-150 owners expect to see 'Dilard Lite'? http://www.avsforum.com/ubb/biggrin.gif
I would be very interested in other opinions of the various LT-150 color matrix settings using Avia (or even Video Essentials for that matter). As always, YMMV.
