Windows Movie Maker not detecting codecs

I can't get WMM on my Vista Ultimate x64 machine to work with input
formats such as XviD, or X264. I have tried installing a codec pack,
which worked just fine on my Windows XP machine (about a dozen new
filters showed up on the WMM compatibility screen), but on Vista,
nothing happens. When I install the codec pack btw, it DOES allow Media
Player to play them, but not Movie Maker. Why isn't it detecting the
filters?

Any advice?

Nevermind, problem solved, all I needed was K-Lite Codec Pack 64-bit
Add-On
