On the previous page Kaosjm was able to rip the full bitrate DTS track from the PIBF-91219 release. This has been stated as a CDS track but is still in question because we can't get confirmation. I've listened to this DTS track and the confirmed AC3 CDS track from the first DVD and can't make a decision. They do sound the same, and to me the CDS track sounds very similar to any of the other tracks. It's too hard to tell without someone very knowledgeable on the subject.
I even contacted hairy_hen who also from the previous page seems to be the guy who can figure this out for us. Though unfortunately there has been no reply for quite some time.
I've been having computer problems on my main rig where I have the file and it will probably be some time before I get that up and running again. Kaosjm might be able to provide the DTS file again to anyone interested if you PM him.
