Here's something for you to try in Chrome. (or Firefox if you want to
try also)

This is a short video my wife took with her iPhone. She claims she has
learned how to play our piano. :-)

It was originally a .mov file in her iPhone.

I converted it to an .avi file and then to a .wmv file using Windows
Movie Maker.

Then, I uploaded it to Photobucket. If you right click on it, it shows
it is playing using the Adobe Flash Player, however Photobucket lists
it as a .mp4 file.

Be interesting to see if your computer can view it in Chrome or Firefox.
