AirPlay on XBMC[]
Observed an AirPlay over Ethernet problem on XBMC 11.0 -- see this thread on the XBMC forum.
Installed XBMC 12.2 via PPA, and AirPlay over Ethernet is successful.
Needs to install the packages in one-by-one manner within the Software Sources page of the Ubuntu Software Center, though. TinyXML shall be installed in the first place.
