As I mentioned, this track should be the default track for the BD25,
which includes the DTS Core, the PCM Laserdisc audio next and then the
dubs.

I disagree that it should be default however. A modern remix is automatically lower in the food chain than original theatrical audio, lossless or not. But it's Andrea's project so I'll leave that choice up to him...

Seconded. I think the theatrical stereo might be a better default, as this does seem to be a theatrical preservation (restored audio and color timing, etc).
