Your classid and probably your local settings for mp4 are all pointing to QuickTime. You need to import the mp4 into a Flash program, then export it as an .swf from Flash. When you publish from Flash, it will generate the (sorta) correct HTML code. If you don't have Flash, you can use Swish or SwishMax.
