The official LCA "Linus getting dunked" video is available here. The version that'll end up on the DVD will probably have multiple angles (linus-vision!), but this seems nicer than what's already floating around out there. Mirror it if you wish, but the guy insists this server can take a beating :-)
I'm the guy doing the video editing and the DVD (fun, fun), so I'm super, super keen to get feedback on how well the file plays on various people's players, I'm proposing the same format. It's a MP4 file, which should play on most Linux/BSD media players compiled against a recentish version of ffmpeg - it's been supported for yonks, and seems fine here in xine/mplayer/vlc. It also appears to play fine on a stock standard XP/OS X system in their default players.
