Apple release HBO Go for Apple TV today but you cannot activate it with DirectTV. Activation has to be done in a browser and not the TV itself using a code from the device. I am led to believe that this is DirectTV's decision as they activate on XBoxes. Very sad as the Apple TV UI is a million times better than DirectTv's on demand UI which is IMHO horrible. If this is not fixed then it could accelerate the move off DirectTv for whom I have been loyal to for almost 15 years.
