I do this for my Roku which has a private channel that queries my
mythweb and will play an .mp4 on the Roku.  I will post you to the
thread on the Roku forums that has a modified script written by a user
there that uses Handbrake and its' ipod specs that will autodetect and
crop your picture, transcode to h264, and then update the myth database
pointing to the new file...
