"Black Snake Moan" uses the same AVC-1 encode for both Blu-Ray and HD-DVD so I expect them to have the same PQ

However, the HD-DVD has an extra DDplus soundtrack, presumably because the Blu-ray is a single layer 25G which presumably didn't have the space. In this case, the HD-DVD's better storage allowed for a better soundtrack. Now if they had used a 50G Blu-ray disc, it would be an different matter entirely.
A better example might be "Nature's Journey". a music video which tries to maximize the available storage/bit rates for both Blu-Ray and HD-DVD. Both versions use VC-1 and DTS encoding; the Blu-Ray uses the higher bitrate encodes (lossless for audio). I expect the differences to be subtle, but perhaps noticeable in the better HT setups.
