Example will use Flash player to show .mp4 (H.264) video clip using OBJECT and EMBED HTML Tags:
In this example, I use the .mp4 file directly. There is no need to re-name to .f4v or add some adobe wrapper.

I am using the jw player player.swf file (free for non-commercial use (effects only smythies.com server, does not effect users)):
I do not need to, but I force use of version 10.0.22.87 of the adode (macromedia) Flash player in this example. (you might as well upgrade anyhow).
There are various edits to this HTML source, as I try to get rid of two errors that show as a yellow information triangle on the bottom left of the IE window. It works, but I want to get rid of the errors and get it to autostart.
