  The issue with making movies for 3D projectors is that there
currently isn't a low-cost encoding mechanism for this type of media.

There are a bunch of competing proprietary solutions, but nothing
that you can reliably use with off-the-shelf software.
I do occasional consulting for a business that develops various
production tools for Hollywood, and one of the tools I helped develop
previously was a 3D movie player that works with the standard digital
files that the movie industry uses. All of the code I wrote was 100%
custom because there still really aren't any widely-adopted standards
other than for Blu-Ray. The most common free/low-cost methods are currently:
  - encode 3D as two separate movie bitstreams
  - encode 3D as a single movie bitstream, using above-below image formatting
  - encode 3D as a single movie bitstream, using side-by-side image formatting
  - encode 3D as a single movie bitstream, using frame-sequential formatting

All of these require special player software...

The new Blu-Ray 3D format uses H.264/AVC with multiview video coding.
So far as I know, there are currently no free or inexpensive MVC-capable
movie encoders in existence. Most of these things currently cost >= $5,000
last I checked. At present, the only way to do 3D movies is to either use
expensive commercial encoders and players, or roll-your-own with your own
custom player.
