Was the video itself sent to your email or was it a link? In the later case you can copy and paste the adress like text, I think, it depends on how the email is shown with the program you're using.
If it's a small clip then you might be able to attach it here, not sure what the limit is here.
Speaking of small clips I remmeber the clip of the absolute nutter (british term) that flew under the Eiffel Tower several years ago, in a bonanza I think, the video is taken from inside the plane as he goes under
And as the story I heard goes, it was after he took off from the airport and he then headed straight out of the country since he didn't have permission and there's a warrant out for him or there was. Even being well before 9/11 I think the people in the tower must've been scared out of their wits.
