Meanwhile, here's a Perl script that I've knocked up that will recode anything you can throw at Mencoder to produce a 300kbps video 96kbps audio 15fps video file, at 320x240 or 400x240 depending on aspect ratio, with vertical or horizontal bars added if need be. You'll need Perl, Mplayer and Mencoder installed.
