How do you set the the DVD and media titles to display in the Info window in windows media player - I can't find this for the life of me.

Thanks

P.S. I see now that this is not done for commercial releases - so I guess it's not possible - anyone know if this is correct?
(I've searced high and low but can't find anything on the Titles and Chapters displayed by Windows Media Player and where they are derived from)
