Why two files? That's not going to make any of the work any easier.

IMHO that's outside the topic of c.a.embedded. Google for Charles
Poynton's Color FAQ or go over to comp.graphics.algorithms to find its
regular posting.
In short: you'll have to interpolate up from YUV422 to YUV444, then
convert the result to RGB.
Not that on most modern PCs, you don't even have to do that yourself.
As most video content is in YUV format, the OS and even the graphics
hardware now have support for this file format.
