Thanks Raul, I suppose that is possible, but I would have thought that Linux would have a way of dealing with .mp4 files. The error of not finding a multimedia control in labsel makes me think that it is looking in the lab selection form for the videoviewer controls. This is why I suspect a 'ghost' form, but I appreciate your suggestion as it introduces other possibilities.
