It's always weird to read codec commentary from broadcast people; their world and concerns are just so alien to me. I also rather wonder what he considers a raw bytestream that HEVC has and VP9 doesn't...
Anyway, I guess the only major concern from him is the DCT overflow? I mean, for the extra precision, even HEVC has increased from 16-bit intermediates in the newer profiles. I think Daala's transforms would solve his issues with VP9's, I'd imagine they're being considered.
