Or for those stuck on windows, www.myhtpc.net. It's easy fast and works great with all your MSWin(tm) hardware. I use it with an Athlon 800 on Win98SE with an IrMan from evation.com and it runs everything i throw at it just fine. It even has Project64 integrated into it, so i can just use my remote to start my N64 games. Great picture viewing options too, metadata support so you can add info to movies and music, and xmltv support. All without the hassle of a linux setup.
