A word of warning.
I ordered an official copy of this film from a web site, not knowing it was based in Canada, where this film is legally available.
After receiving not one, but two empty cases, I got the message and had the third order brought from Canada as the private property of a Canadian tourist.
This chapped my hide to the point where I know of a person who will offer free copies of this film to people in the U.S. who qualify.
Incidentally, this film is readily available also in Great Britain. Just not in the U.S.
I bought an official Disney copy of SOTS in PAL format from a shop in the UK about six years ago. I had to take it to a local electronics shop to convert it to an NTSC-format VHS that my American VCR could play -- the shop assured me if I made the transfer for my personal use, it was all legit.
But it was kind of expensive -- the UK PAL video cost me about $50 after currency conversion, and about $25 for overseas shipping, then add another $20 for the format conversion.
The quality of the NTSC conversion wasn't all that great. So let the buyer beware: make sure the copy you buy will play in an American VCR, or be prepared to pay for a conversion (I knew when I bought my copy I would have to convert it).
