I have been reading up on the new Apple TV and it sounds awesome. My questions is, I have about 120 movies that I am wanting to rip to my MBP hard drive and stream to the ATV. I know the ATV plays the movies through iTunes, but I dont wanna leave all these movies on my laptop eating up valuable HD space. If I get a 2TB external hard drive, is there a way to move the movies over to it, and then have them show up again when it is plugged in??
