The computer I had synced with my AppleTV died an inglorious death some time ago. I have never re-synced the AppleTV to another computer for fear of losing the media files already on the AppleTV. Now that I today installed aTV Flash, can I use FTP/Cyberduck to get the files off to my MacBook?
Yes, you can recover these files by connecting via SFTP. A detailed guide can be found at the link below.
