Only 1 Nintendo console used carts instead of an available disc format; the N64. The CG used a propriety mini-DVD and the Wii uses DVD9.
Sorry about not being able to watch movies on it but you can buy a $20.00 DVD player from Wal-Mart. I'd also think that's hardly a reason not to like their systems considering the games are the core focus of any console.
