I did the same 2 weeks ago, I think XMBC V1.0 is awesome as a dash!
I did leave evox as a secondary dash though. Basically you need to copy your XboxMediaCenter.XML and your Default.XBE file to the root of your C: drive.
to keep Evox rename evoxdash.xbe to whatever you want, I renamed mine to evox.xbe
Also here is a copy of my XboxMediaCenter.XML because there is a couple changes to make Evox a 2nd dash. Use Wordpad, not Word to modify your XML.
I hope this helps!
