don't know how to handle video/x-dvd-subpicture
And, no, I don't think I want to use xine or mplayer or whatever instead. I think they all have pretty lousy UIs, and mplayer in particular has also proven to be rather unreliable. I know one application that generally just works most of the time, though: It's Ogle (http://www.dtek.chalmers.se/~dvd/) Some of its features are incomplete, however, and it seems like there hasn't been a lot of development lately, and I've come across one DVD it won't play, so I thought I might try something else...
