I think cost and simplicity are the 2 big factors in
implimenting a decent sound system. If you really
could run it right off the optical sound head without
conversion and all you needed was software for a
laptop it could really work.

You could make a cd or dvd that had both the
soundtrack, the software and the operating system on
it so the venue wouldn't have to install software,
like those liinux things that run off a cd.

Then it would just be a matter of connecting the
laptop to the projector and amplifier.

There is still the cost of making optical prints sadly

...and basically I think DTS would have to give it
away, or maybe charge $20 for it at most. :( That or
they would have to at least do something to seed the

I do think it would be great to have a simple sync
system tho.

How about a system where a computer plays a sync sound
whenever the film has been marked with a felt tip?
Could that be done? :)
