After some investigation, it looks like whatever it's using to pull the codec information doesn't seem to fully recognize TrueHD. Verifying through XBMC, Track 1 is definitely TrueHD, Track 2 is 5.1 AC3, and Track 3 is stereo AC3. According to ViMediaManager there are only 2 audio streams, and both are plain AC3, one with 6 channels, and one with 2. I believe this is because the TrueHD track used in this case contains a 5.1 channel AC-3 core, which XBMC recognizes as a separate entity.
I tested ViMediaManager out with the Catalyst demo from here:
http://www.demo-world.eu/trailers/high-d...ailers.php
And ViMediaManager shows it as 8 channel AC-3, so it may just not be differentiating between the various AC-3 codecs like it does for the various DTS codecs. (Edit: My mistake, it looks like it doesn't differentiate between the various DTS codecs, either. It looks like the files in my library that correctly indicated DTS MA were generated with a different program. Edit 2: It correctly pulled TrueHD codec info from my 21 rip, so it does recognize it sometimes. Weird.)
Typically track order is sufficient (highest quality tracks are always first on studio Blu Rays/DVDs) to determine quality, at least for studio releases. If you need help with any of this let me know.
Also, thanks for the trailer info. I'll just run the full update and see what happens.

I guess you're suggesting the order of quality is DTS-HD > DTS (core) > AC3/DD > AAC ?
I have seen people argue that AC3 and AAC is or can be just as good quality as DTS. Then you layer on the issue of number of channels, so it is a bit complex.
Mainly I just forgot the slashy between DTS and AC3, and I never said anything about AAC. The max bitrate of AC3 is 640kbps, and the max bitrate of DTS is 1500kbps, though the difference is not as large as the bitrate discrepancies would make it appear. At their maximum bitrates both are quite good, but I can't say I've ever seen a comparison where AC3 won out.
For the codecs I mentioned, number of channels isn't really a complicating factor either. TrueHD, DTS-HD MA, and DTS all require a minimum of 5.1 channels. AC3 has a maximum of 5.1 channels, so you'll never find a case where AC3 would be the better choice merely because it has more channels, for example.
On top of that, studios are very deliberate in their encoding due to licensing restrictions. On DVDs with DTS, it's always the highest quality encode, which is paired with a lower quality AC3 track for compatibility. On Blu Rays, one of either DTS-HD MA/DTS, TrueHD/AC3, or raw PCM/AC3 (in the early days) is chosen as the primary/secondary track. They're never mixed, though sometimes secondary languages and commentary tracks are encoded in AC3 on DTS-HD MA discs.
