Wait, they were new mixes? Why?

Because DTS digital at the time thought creating new dts mixes for all the films was the way to go. I guess they created new lossless ones that they would have used on the blu ray's had they been released.

The higher bitrate on the laserdiscs is supposed to blow the UE audio away. But with the new tech of blu ray that would obviously be no contest were they released.

I would love if films would have both the theatrical dolby and dts mixes. It pissed me off when they released the star wars special edition on laserdisc without the DTS version, or the dts version of Star Trek first contact.

Then the Blu rays did not even have the stereo mixes for the original star trek films with the old crew, they were all like 5.1 or something. Also they did not preserve the 70mm mixes either, the 5.1 was based on them but not identical.

When i watch star trek the motion picture i have to watch the laserdisc because the dvd mix for the theatrical version sucks.

Just like i was recently listening to the theatrical stereo mix for the wrath of khan in analog on the first laserdisc pressing and it sounded great, while the digital mix on the dvd sounds too clean, digital and lifeless.
