I have an ATV3 and a MacBook Air 128GB. I love my MBA but it just doesn't have the HD room I need to house all of my media (I'm about 25GB short). I have a 500 GB WD Passport external HD that I use to back up and store everything. 1. I'm almost certain the answer is no, but is there any way to serve my media off of that external HD? 2. If I replace my router and external HD with a Time Capsule, could I serve the media directly off of that somehow? 3. Any other options I'm overlooking here? I've run a few different programs to remove language packages and things like that to free up space on my MBA, so dropping my media on there just isn't an option.
