FWIW: I'm using a Toshiba 3D-camcorder which records the images in NTSC 
format. Here in Germany, we use PAL as TV-standard, and I am using a 
Panasonic VCR to playback the NTSC tape on my very old (>15 years) TV-set. 
Works fine, although (obviously) more flicker is noticeable due to 50 Hz 
used in Germany vs. 60 Hz in the USA.

I have, however, not tried to record the image on a PAL VCR and play it 
back from there...

I've seen a brochure of Andrew's converter, and it really looks like a 
neat piece of equipment if you are into more professional aspects of 
alternating-frame stereo viedo .
