        Good to hear that you are back in action after the system/disk crash 
        of not too long ago.

        What is commonly called "YUV" is really Y'CbCr where Cb is the blue
        difference and Cr is the red difference signal.

        So my guess would be Cb - see the 4th paragraph on the reference
        above for more info

        Cheers,
