Indeed, I had the opportunity to attend a special 'Transformers' media event with Paramount late last week, and the question was asked almost immediately -- why no Dolby TrueHD or uncompressed PCM? The studio's answer was that due to space limitations on the disc, the decision was made to limit the audio to Dolby Digital-Plus 5.1 Surround only (here at 1.5mbps). Unfortunately, this confirms the long-held theory that the 30Gb capacity of an HD-30 dual-layer HD DVD disc has forced studios to choose between offering a robust supplements package (as they've done here) and the very best in audio quality.
That said, it is hard to imagine any film taking a Dolby Digital-Plus 5.1 Surround track to its zenith better than 'Transformers.'
Note that although I'm giving this audio mix five stars, that doesn't mean I agree with Paramount's decision to forgo high-res audio on this title. Without a TrueHD or PCM mix to compare this one to, there's no way of telling how much better such a track might have been, but based on the upgrade I've seen with other titles, I'm guessing a high-res mix could well have trounced this one. That's not to take anything away from this truly exceptional mix, but this is one case where I think you truly can improve upon perfection.
