On U571, the DTS soundtrack's LFE is 4db higher than the LFE on the Dolby Digital soundtrack. No one really knows which version is actually correct. Many feel that the DTS is too high, since it hadn't been long since the screw up with JP DTS being 4db too low. But then again this time it could be the Dolby track being 4db too low. I personally feel the DTS track is more accurate to my theatrical experience seeing U571. So basically, we don't really know which is the more accurate, but the LFE is 4db higher on the DTS than on the DD in the LFE channel on the U-571 dvd.
