Region 4 dvd—any way to watch it?

I recently bought the dvd Besouro, and on the back of the box between the dolby digital and dvd video logos there is a small rounded square with a four inside. I am guessing that this means the dvd is region-4 encoded. Is there any way i can still watch it? Is there anyway to get my imac to work for this without breaking it? I don't really want to mess around with my dvd player or computer unless it's side-effect free.
