The MPEG bitstream contains flags indicating the TV system that the video
is formatted for. In a non-converting player, this must match the system
of the player or else it returns an error (like "cannot play this type of
disc"). A player capable of dual TV systems may reformat the output for
more appropriate display on the other system.
