Everything runs smooth on the 3.6.3 version. I do have some .mkv-files I do want to play, but when I try to install the VLC Player I get the «an error has occured» message. Is there anything I can do to get the player install, or is this a bug?
I would FTP into the Apple TV and see if there is a VLC application in the Applications folder. If there is, I’d delete it and then reinstall VLC from the Maintenance window. Also if there is a VLC DMG file in the frontrow folder or in the Documents folder, I’d delete that as well. Probably just a failed download.
