I'm probably being very stupid, but here goes anyway .....
I downloaded the file, and some 'decompress code'(?) programme it offered me, but the video won't play except in short 1-2 second bursts, and then stops while it's "buffering".
I'm using Intel Pentium P4, 256 MB Ram and (from memory) a Geoforce(?) video card.
Any ideas from the boffins?
