Streaming movies to an xbox 360

Hi I'm new here so please be gentle. With my pc I could stream movies thru my xbox and watch them on tv in my living room, is it possible to do this with a mac? I've just bought a mac mini

Yes you can:

I'm not sure if what pigoo3 posted is what you were looking for, but my guess is you're trying to get your XBOX to talk to your Mac like it talks to Windows Media Center.

I bought an excellent utility called Connect 360:
Nullriver Software : Products : Connect360

This lets me browse predefined Mac folder using the XBOX UI.
