On the Terminator 2 Skynet Edition forum on blu-ray.com someone said they had a dvd that included the CDS Mix in full bitrate DTS. From some searching it seems to be the R2 Japan-Geneon Special Edition.

The DVD is unfortunately out of print and I can't find a rip of this specific DVD anywhere. I messaged the guy on the forum if he would be willing to share but he won't respond. The DVD looks like this and the picture he posted was of this same DVD.

Anyone have any knowledge of this disc and or have a copy or know of how to obtain this CDS Mix in DTS? From what I gather it would be one of the best if not the best option for the CDS Mix rather than the AC3.
