Glad I could help out with this. :)

I believe there was a question about audio bitrates . . . the '85, '93, and isolated score tracks are all stereo AC3 at 320 kbps, while the theatrical mixes use lossless compression and therefore have variable bitrates. The core DTS tracks contained therein are at 1509, 639, and 384 kbps respectively for the 70mm, stereo, and mono.

My reason for going high on the cores is that legacy DTS compresses audio quite differently than Dolby Digital, having been designed to provide maximum quality within a CD-ROM bandwidth rather than trying to squeeze it down to as small a file size as possible. It focuses first on compressing without actually removing information, and only then uses perceptual encoding (throwing away parts of the sound that are difficult to hear) in order to get down to the target bitrate. As such it requires more bits to function effectively, and comparing it to AC3 on numbers alone is meaningless. With 1509 being virtually transparent for 5.1, I wanted the stereo and mono versions to be comparable, and those are the numbers I arrived at.

Using larger cores does increase the size of the output, but since DTS-HD MA is providing lossless and lossy audio together in one file, that can't be helped if the goal is to obtain maximum quality from both. I did some brief testing and determined that the file size is actually quite comparable to encoding in Dolby TrueHD and including a high bitrate AC3 track along with it, so in terms of total efficiency for a dual delivery system, both come out approximately equal.

Anyway, I hope everyone will be happy with the soundtracks included in this release, and enjoy being able to switch between them without the volume levels jumping all over the place. ;) I'll be making a new thread for all of my stuff where I can discuss them in greater detail if anyone is interested in hearing more about it all.
