Seems the Theora version really didn’t want to play outside of Quicktime. Courtesy of ffmpeg, here’s a DivX version that works in VLC on Gutsy out of the box, at least (just checked it)… poorer quality and the aspect ratio’s gone a bit squiffy, but what the heck. I don’t really function properly before 10am, and it’s really not that exciting anyway 🙂
EDIT: Thanks to Arek for pointing out the blindingly obvious, here’s a proper Linux and Solaris-friendly OGG version. Yay 🙂
