No, I've spent some time playing with it now and it seems only mplayer has 
this problem.  If I run "less -f /dev/dvd" before I load mplayer, then play a 
DVD, pause it and wait for the drive to spin down, then if I unpause it 
mplayer locks up as I said before, however I've now found that if I scroll 
around in less a bit the drive will spin up again and if I then unpause 
mplayer it keeps going fine.

So it seems as though the way mplayer is accessing the drive isn't causing it 
to spin up again (which I believe the drive does automatically as soon as it 
gets a read request.)  Is it possible that the kernel is putting the drive 
into some kind of sleep mode or something which doesn't get deactivated by
