(I can see this post, now, at least!)
Was your video file in one of theses formats: asf, avi, divx, flv,
m4v, mov, mp4, m4v, mpeg, mpg, wmv, 3gp, 3ivx, 3vx? and did you
paste the link into the box where it says, and then did you click
on "Import"?
I'm not sure what happens after that, as I've never done it, but I
should have thought that would be it. Good luck.
