That's old news, I used ATV flash to install XMBC, Boxee, Couchsurfer Pro, and Perian Codecs as well as enable the USB port for a RF wireless keyboard with touch pad. It all works fairly well but Boxee takes 3 min to load due to the ATV's slow processor speed.
It just dawned on me you might be confusing the 2nd gen ATV with the new 4th Gen one without a HD.
any body know how?
