* Fixed crashes on exit in the directx plugin
* vout_PlacePicture is now accepting picture width=height=0

* Win32 (NT/2000/XP) fix for libdvdcss: first attempt to open the DVD
  device in read/write mode so we can use ioctls. If this fails
  (insufficent privileges) we at least open in read-only mode so the
  libdvdcss title decryption method can be used.
