How to change audio track comments on a .ogm?

[CydeWeys]

I ripped a DVD of mine to .ogm since it had two audio tracks that I was interested in (main audio and director's commentary). While encoding, I messed up on the Comments section of the audio track so that both are entitled "English" instead of one being entitled Director's Commentary. The comment is what shows up when you go to the Audio track menu in a media player. Everything else about the encoded file is fine (audio and video included), but that one audio track comment is off. I don't want to have to re-encode the whole thing (it took six hours), so does anyone know of a utility to modify the audio track comments in a .ogm file? Thanks!
