Okay I don't have more electronics knowledge, so that's why I try to
be resourcefull instead! I don't know how accurate this would be, but
I have noticed when shooting pics (higher than 1/30, most likely),
with the TV in the background, the scan lines (from the TV screen) are
visible in the photograph. It would seem to me that if the shutter
sync was off, the scan lines would not match in the left and right
images.

I notice this when I shoot pictures with my twin P&S, but surprisingly
the scan lines are only an inch or two displaced from each other most
of the time.

P.S. What kind of dog is in your stereo picture. (and don't tell me it's
an ascii dddog! ;-)
