Yeah I have it hooked up to my TV so I can watch stuff away from my PC, I put a 120GB hard drive in it and XBMC runs FileZilla FTP Server so it's easy to FTP things across. It also have full access to the Internet so you can stream nearly any format as long as there is no DRM on it. It can also access NAS devices, windows shares, iTunes shares, nearly anything. They are porting it to Linux at the moment, there was talk of a 360 version but I don't think it's feasible plus I wouldn't want anything that loud in my living room whilst watching videos.
So I can install x64 Components and run the 32-bit media player? Why does it contain some codecs for the 64-bit player, do some people run both of them?
