HI All, There are a bunch of people having trouble getting xbmc installed because of a 404 error. so here are the commands with the mirror.
You need to SSH into your ATV. If you dont know how to do this then LEARN that first… Google is your friend.
here are the commands.
mkdir -p /Applications/AppleTV.app/Appliances
apt-get install org.xbmc.xbmc-atv2
mkdir -p /Applications/XBMC.frappliance
dpkg -i org.xbmc.xbmc-atv2_11.0-3_iphoneos-arm.deb
