Well, from my point of view that's silly because hardly anyone cares the
slightest about those extra 2 bits and thus I expect nobody in the foreseeable
future will write pixfmt support for them (I just see someone in 2007
gave up at that point), but I don't really care, though I do find it a
bit sad that those people stuck with hardware to create it must beat
some Quicktime components or Windows dlls to get them to work with
MPlayer (and no, those certainly don't output with more than 8 bit per
component) in order to use this format.
Anyway, I have at least finally created a page on this format on the
multimedia wiki, so hopefully the next person at least won't start from
