I found that creating a raw dvd device (i.e. character instead of block)
improved my performance (with xine). I haven't tried the same with
mplayer, nor do I know if mplayer takes advantage of raw dvd devices or
not. (Someone in the know feel free to comment)

I'd second (a) above as well, have you RTFM yet? (BTW, does the mailman
signup page have an RTFM comment in it? Maybe it should, as in "Before
posting to this list you should RTFM". That might be a more productive
place to put it, if it isn't already there... I really should check
before I post ;)
