YUV to RGB conversion using ATI_text_fragment_shader

Hello,

I currently have an application that decodes a YUV movie of type
k422YpCbCr8CodecType
into a GWorld that is textured using GL_YCBCR_422_APPLE,
GL_UNSIGNED_SHORT_8_8_REV_APPLE,
I would also like to process my video stream (on the card) using
GL_TEXT_FRAGMENT_SHADER_ATI.
Reading a earlier post from this group from someone at ATI, it appears
that I must first pass
my video stream through a YUV -> RGB conversion shader. My question is
how to do I do this ?

Documentation about ATI_text_fragment_shader in general (specifically
for color conversion) on
the web is 'lacking' (yes, I've seen the registry), so if anyone has
any sample code, tips or
tricks on how one might accomplish this, it would be greatly
appreciated.
