View source for Install Perian

This guide is basically [[NitoTV#Manual_Perian_Installation|from Nito]], but it's probably useful for people not using [[NitoTV]] too. This guide assumes you will do all of the work on the Apple TV, accessing it via SSH. It has been updated for Perian 1.2.3.
The QuickTime 7.6.4 update bits allow Perian to accelerate the decoding of h.264 content without compromising youtube and podcast functionality.
