OK - I've confirmed the problem seems to be that the codec parameters aren't set, attached is a quick-and-dirty patch which "fixes" libx264 output by setting up the codec parameters.
After applying the patch choosing x.264 video within an mp4 container (haven't tried other containers yet) produces a file with both audio *and* video (which plays OK in mplayer).
Although you could, perhaps, use this for v1.1 I think that there should really be some way of editing these. Certainly for x.264 and probably there should be a more generic "advanced codec configuration" dialog.
