I wish. I am huge DTS (especially the ES 6.1 if you've got the equimpent) fan. It is a DD EX soundtrack, which is the best Dolby Digital has to offer, but I think the much higher bit rate and the fact that in the US there isn't as many DTS supporters as abroad left DTS out. I got the Donnie Darko Director's Cut and the R2 version has DTS, while we get DD. In Asia they are fanatical about DTS soundtracks and use them much more than here. Maybe when we jump to the next format with HD-DVD and Blu-Ray, we'll see more liberal use of higher bitrate audio (especially when mixing an additional channel for the 6.1), but right now you may sacrifice your video quality (movies like Brotherhood of the Wolf had to do some compression with the addition of the DTS). Also think about how much room those animated menus take up on the 2004 Box Set, very significant amount of space. Ultimately though I believe THX is tied in tightly to DD and probably will never go DTS. Which is sad. I feel it is superior to the best DD has to offer and many other audiophiles agree. Where did you get the aforementioned disc though I'd love to hear the two tracks played against each other (one with the DD EX and one with DTS).
