This plugin for winamp is ancient, and never got updated when DTS started encrypting their CD-ROMs after about 04-05, so only films prior to that with DTS tracks could be utilized.

The plugin you used: is it called APT-X100 DTS Decoder? I remember finding this the last time the '97 SE discs appeared on eBay, but as the seller was asking silly money for the discs I didn't pursue ripping methods at the time.

You are correct that the encryption that was introduced c. 2004 was never cracked, and later discs are still unrippable.

Well done for this. I can't think of a better example of a theatrical DTS soundtrack - I still remember seeing that "Digital Experience" bumper in the cinema, too!
