i still would rather have special features over sound and picture quality when given the differences on superbit...
the only disc i own that i find the DTS to absolutly blow away the Dolby Digital track would have to be Saving Private Ryan...
every other disc i own thats in DTS, i find is still better than the DD track but doesnt really "wow" you...
i usually use Saving Private Ryan as my "sample" disc when people ask what the difference between DTS and DD are....
they notice the difference immediatly
