Got my new iMac on thursday and I love it. It's the base end 21.5" and it's faster than anything i've ever owned before, hah. But here's my question: Is it possible to rip the DVD's I own onto my iMac and play them through iTunes without the disc? I ask this because I own A LOT of dvd's and it would be more convenient to just have them all on the computer instead of having to constantly change discs when I want to watch a movie. Thanks!
