From what I read, you need version 1.6e, because they broke DTS in version 1.6f. It's on the site I listed, just scroll down a ways and you'll find it. There are 2 versions for 1.6e, I needed the Neon version for my phone. Yeah, just install it from the file manager in your phone/tablet after you copy it to a folder on your phone/tablet. Don't forget to go to Settings - Decoder and check S/W audio.
I downloaded the free version (with adds). They also have a pro version after you try it and like it!
