What is the most efficient way to convert a .wmv video?

[joe at actionline.com]

Just tried to download it, but it didn't seem to work.
At least I can't find it on my system.

http://vimeo.com/63481216
Download jihadi.blows.up.vw
    SD .MP4 file (452x360 / 1MB)
    Original .WMV file (320x240 / 626KB)

What am I doing wrong?
Curious that the file name has a space in it? "SD .MP4" ??
