The DTS-6 can be made to play discs without film. If you wanted to record from it, you'd need a proprietary analog cable (DB25) and a 5 channel recording mechanism. I really don't think it'd be worth doing things that way.
Also, I can encode DTS-MA or Dolby TrueHD, but DTS-MA is much easier work with and the app itself is far easier to use.
