I have a late 2012 Mac Mini 2.3 (or 2.6, I can't remember) i5. When I do a conversion in handbrake from a large .mkv file (20-30GBs) to ATV3, it will literally take 3-5 hours per movie. I'm only averaging around 9-10 fps per movie. Other than a new processor/motherboard, what can I do to speed this up? Sometimes I will have 7-9 movies in the queue for handbrake and it will run for a couple of days before it is finished.
