Hi Omega. Just for the record WMP11 streams to the PS3 straight out of the box, so no fancy set-up is required.
TVersity works better in general for streaming to either XB or PS, if you are willing to tinker a bit, especially for MP4 streaming which WMP11 (or Media Centre ofr that matter) doesn't do by default. You need a windows registery hack for MP4 library listing support (that only works sometimes).
"PS3 media server" is also a decent app, and supports the Xbox as well these days. But it needs the Java runtime on the machine which adds to the installation hassle in most cases.
