Wont play any video

The install appeared to go well but I cant play any video. I did ftp the CoreAudioKit.framework to the atv. All add ons appeared to install correctly.
Internet browsing works well through couchsurfer and Nitotv but again no video playback on either (youtube, hulu, any internet content).
It would appear that I’m still missing some codex or add on.
Any ideas?
