I've been converting my blurays to digital m4v's and it's been slow. I was using the "Normal" preset and the time it took was almost equal to the length of the film. I've recently switched to the AppleTV 3 because I like the idea of keeping 5.1 surround sound audio which Normal didn't do. Encoding now takes about twice as long. I'm using my 13" MBP which I know is only dual core. Question is would I be better off to just pick up a used quad core laptop on Craig's List for $150 and use that solely for encoding? I rip the movie from BR to MKV using MakeMKV then encode that mkv file using Handbrake. 4 hours to encode a movie is a little excessive in my opinion. Thanks for the advice.
