Comment 16 for bug 946799

Update (on Ubuntu 12.04, 64 bit, for use with iPod Classic 120GB): Some video now working.

Have compiled 2.1.2 unstable, and though it crashes occasionally (when adding an unsuitable filetype, for example), mp4 videos can be added successfully - generally. In preferences, plugins supporting mp4 and m4a files can now be selected (I no longer get the 'installation is corrupted' error message), but m4a files do not seem to transfer usefully: although they apparently transfer to the iPod, they cannot be played.
