Decoding surround in mp4 or dcp to analog outs?

[Ted Blaisdell]

Hi,

I'm not sure where to post this, so here goes:

I occasionally do live sound at a 200 seat theatre. The theatre also has a big screen, a digital projector and a discrete 5.1 sound system. They have a few movie screenings every year and lately, instead of getting a dvd, they are getting sent mp4 files of the films. They have also just been asked if they can accommodate dcp playback.

My question is: Is there any way to decode the six channels of an mp4 (or dcp) file at the computer into separate analog outputs so I can route them to the proper speakers?

Thanks!
