It's time to update this topic... I'm just doing the DTS soundtrack - taken from laserdisc, obviously - of "The Lost World: Jurassic Park", and it's awesome also on hearphones...
Whoever is interested in the JP1 (released) and JP2 (available soon) DTS soundtrack, is free to extract them from the BD version. Don't know for sure if they match 100% with DVD or BD video, though!
