I put on the DTS 6.1 track on the new extended version of LOTR and found the bass was lacking. I took it out checked the calibration, everything was normal. I then checked my samson amp, I have a SVS sub, again everything was fine. I popped in AOTC and thought wow with the opening ship scene. Switched to DD on the LOTR disk and the bass was there right away. A huge difference, could this be a bass problem like the one on the initial release of Jurassic Park? If you are having the same problem please let me know.
