Comment:
The error is indeed in the weight table for interlaced blocks, and should
impact the decoding of any such content. I haven't checked the encoder.
On the other hand, the weight tables for 8x8 and 2x4x8 (non-HD) have
values somewhat diverging from the mathematical ones. I wonder if that
would be related to simple idct, but on the other hand they are not the
inverse of what the encoder use.
