I have been running XBMC “Eden” on all of my Apple TV’s for sometime now with out issue, but the other day I noticed there was a new release called Frodo. Frodo brings some fixes, and changes to XBMC so I figured why not stay updated and upgrade all my Apple TV’s. Usually you can login to the Apple TV and issue an apt-get update but since the new version is still a RC you need to enable the pre-release/nightly builds to get it.
In order to add the new apt source for the pre-release/nightly you will need to login to your Apple TV and issue the following commands
echo "deb http://mirrors.xbmc.org/apt/pre-release/atv2 ./" > /etc/apt/sources.list.d/xbmc.list
apt-get install org.xbmc.xbmc-atv2
