The Pioneer system may be a little different than a simple shutter glass
system and it may indeed depend on motion in the scene without being
Pulfrich.  A few years back we had some discussion of a system developed 
by Baxter Garcia of Automated Medical Products.  It used a single camera 
with the video piped into combination hardware/software which analyzed 
the motion between frames and generated the appropriate field-sequential 
stereo video which was viewed with LCD shutter glasses.  This is a very
clever approach and by all accounts worked surprisingly well.  The
advantage is that the stereo is generated from mono video and any
existing tape or program can be viewed, not just the limited number of 
shows available in stereo.  The disadvantage is that it is not true
stereoscopic 3-D and some things must not work very well.
A $200 consumer system of this type would be very interesting since
besides shutter glasses it requires video digitizer, frame buffers, etc.
I don't know about the Pioneer system but this is what it sounds like
from the description given.
    For the more standard shutter glass system, it is hard to beat VREX's
VR Surfer.   Wireless LCD glasses, software, games, pc and video
interface.  I have some available at $100 including US shipping.
