Media Servers for PS3

I found the aptly titled "PS3 Media Server" in the weekend and installed it on my Mac. Seems to work well.

Are there any better ones for Windows machines that I need to look at before installing it on the living room desktop?

I use Tversity on Vista - works well and last I looked was considered the easiest and best for the PS3. That was 6 months ago but.

Cheers gman, will check it out.
