My mp3info2 is not yet up to the task (oggs are hard beasts to measure
length; the rest should works); the same goes for exiftool.  The
mplayer incantation in the other message would probably work (although
the rest of that message is not very trustworthy).

You should also try mediainfo.

Hope this helps,
