i can tell you exactly why. libdvdread has this idiocy in one of the
function calls which mplayer uses, where it cracks *all* the keys for
the whole dvd rather than just the title you want to play. just edit
dvd_reader.c and "#if 0" out the entire body of the initAllCSSKeys
function and it'll work beautifully.

an even better fix would be having it cache cracked keys in ~/.dvdread
or something, but i didn't feel like bothering with that.
