you may want to track down the R6 DTS DVD of JP as well if your comparing

That was an exclusive DTS track to that region that was 1536kpbs and apparently a different mix. I had it for a while and it sounded superb. very high bitrate as well whilst reading up on it

costs $5 plus shipping

I have the White Box set and they are 755kbps for DTS. It would be nice if someone on the forum had the R6 Japan DTS set as the audio for JP 1 & 2 had exclusive mixes for the region. I also believe the video bitrate topped out @ 9mbps which was the higher than the Superbit set.
