Just been looking at your websites
1. very nice could do with the background slightly darker to show your buttons frames
2. Equally nicer I note the big Q screen of death flatlining too.
I had the same problem too.
The only alternative I can give is either a gif animation of the film or a picture with a link to the movie.
I think the problem is to do with iWeb not writing to the source code.
Have a quick look at mine http://www.oakesc82.calloo.co.uk
You will see my solution in Cartoons and Animation
