I have an Apple TV and I have tried to hack it for use with ISO files and external drive with no success. (Image stutters, drives not recognized, etc) I have been just streaming from my Mac pro- but I prefer not to leave it running 24/7- not to mention the fan noise is kind of a drag when watching a movie. So I am thinking of going with the mini. Assuming it runs quiet- I would not have issue keeping it on. My concern is what kind of image quality will I get compared to what I get with Apple TV? Looking to play SD iso files and itune rentals.
