I have an older first generation Apple TV with 160gb hard drive that I really like and use in my motor home for trips, but the drive is too small. I like that I can store my iTune movies or home movies and access them without the need of internet. However the hard drive is too small, and I want to upgrade to something larger, preferably 500GB. There are websites that show you how, but they seem a bit complicated and I am not sure if I can even go as big as 500GB. Anyone know of any company that does this type of upgrade for a fee? Any alternatives to Apple TV to store iTunes movies? Any help would be great!
