MuseumSteve,
Point taken. I was not trying to imply that DTS is worthless in comparison to DD, but rather that just because the soundtrack is available in DTS, it does not mean you are getting anything better. You certainly might, and you might get better sound from the DD soundtrack. It all depends greatly on the outfit that puts the whole package together and mixes and encodes the stuff for the disk - they can break a good original and they may improve on an original that may have not been set up right.
I personally have no problem with any additional soundtracks on a disk so long as at least ONE of them is good and at least 5.1 if the original audio is available in at least that many channels.
What I do have a problem with, and its getting away from the topic a bit, is putting multiple soundtracks on a disk such that if forces the film to be divided over 2 sides or 2 disks. I know that the DVD standard requires, or so I've read, ( DD and PCM ) or (DTS and at least one of the DD/PCM set) or something to that effect - but is that required 'per physical disk' or per 'disk set' (ie can one have 2 disks both with the full film on them and one disk has DD and the other disk has the DTS - each physical disk only having a single soundtrack format on it?)
People certainly have thier feelings on what they like, and in many cases a person cannot articulate or demonstrate WHY they prefer something other than that they do prefer it. That is fine - just don't shoehorn DTS into the disk at the cost of the video continuity.
