Not possible on most Macbooks which use Matsushita (Panasonic) drives, which force a reading of the region code even in data mode. There are a limited number of drives for which hacked firmware has been released, so if those computers use the drives that can be hacked, they might be able to use VLC or Mplayer.
Otherwise, he's probably stuck.
