as a spherical panorama. I used to shoot ONLY cylindrical panoramas for
years, and ran into this quite a lot. It was confusing until I found
the settings to force the viewer to treat my images as cylindrical. It's
easy enough for the viewer to do this automatically--the give-away is

file produced from a cylindrical input. I had some problems verifying
this as Pano2VR failed to convert the .mov file to equirectangular
properly; the output file was only 1KB! Fortunately, it did manage to
produce a new .mov file which could then be converted to
