I'm just curious if anyone has bothered to rip Blu-ray movies and run them on the rMBP. With how good the screen is, I imagine you could get some pretty good results. Although I wonder if you could really tell the difference between Blu-ray and iTunes HD on a laptop. Still, I prefer iTunes for the convenience/integration and also a good visual digital library on the Mac, and supposedly battery life would be better under Mavericks by watching an iTunes movie. But I do have some foreign movies I am considering ripping, as those aren't on iTunes or have forced/crappy subtitles. Anyone? MakeMKV looks really good, and then HandBrake if you want to compress it.
