Got it; thanks. All that is left now is to read that quantization
matrix structure. I looked at it yesterday. If I understand it
correctly, Y, U, and V planes can each select between several different
quantization matrices depending on intra/inter status. VP3, by contrast,
is able to use 3 total quantization matrices: Y-intra, C-intra, and
inter (applied to both Y&C).
There is also one more incompatibility, or extension, that affects HD
material. Has something to do with superblock run encoding, I believe.
