Emory Kristof from National Geographic actually shot some 3D video
of the Titanic back in about 1992.  He used a pair of underwater
cameras and two betacam decks.
It was shot on the Titanic dive in which the two Russian Mir Submersibles
were used.  The same dive in which the IMAX footage for TITANICA was 
filmed.
I saw the footage displayed on some StereoGraphics equipment
(which uses the side-by-side 3D format) at the Underwater Intervention 1994
conference in San Diego.

p.s. what is JPS LCD format?  

Does JPS refer to the JPEG compression format?  If so, be careful...
JPEG is lossy compression and can therefore lead to crosstalk in 
3D interlaced images.  GIF format would probably be better (unless a very
low JPEG compression ratio is used).

I guess the "LCD" refers to Liquid Crystal Shutter glasses.
The group informally decided to use the abbreviation "LCS" some
months back to avoid misuse of the term "LCD" (because there are
no LC displays used) and to avoid confusion with HMDs (Head mounted
Displays) which do use LCDs.

Incidentally I tend to use the term "3D interlaced" to refer to 
images which are interlaced for viewing with LCS glasses.
