I would imagine closeup means "rip" movies to the drive on the mac and use something like apple frontrow to play them? Probably need to expand your question closeup to get a better answer.
If you would like to "rip" movies to the mac then yes it is theoretically possible. You could then use a piece of software like matinee to play them from one location outputted to your tv.
Remember it's a bit of a legal gray area when it comes to copying/ripping dvd's.
