wmv in header?

I created my site (ugbag.com) using Artisteer. I wanted a video loop in the header, but all Artisteer allows is Adobe flash. Not having the proper software, I created a wmv file, which looks fine in and of itself, then used Prism File Converter (a free dl) to convert it to Flash.

It now looks like pixelated garbage, and I don’t know if it’s the conversion or the low resolution of the Flash file. The header also does not load completely at the start, but seems to correct itself once it loops.

I’m a fast learner, but nowhere near an expert on WP. Any suggestions? I’d like to be able to just use the original wmv video file in the header, and have it loop. Thanks to all in advance.
