I didn't, but it had a full /usr/bin/mythtranscode in there, which
(left over from an old db probably) I've removed. Job still fails, but
now, at least I get a little more info:

Unknown codec appears to be our winner. Playback works fine, so myth
has no problem, but transcode apparently does. Here's a little mplayer
verbose data on file .. only thing I know of to get more info about
it.

Hope this gives you some information to work with. Thanks again for
taking the time to take a peek at this.
