As media is progressing more and more into HD, .mkv format has become a popular container for high def video. Why is it that there are only three major players available for OSX that can support .mkv? And to be fair, neither of the three are hacking it on my MBP. I have a Core Duo 17'' MBP with 2gb of ram, and yet i cant watch a 720p movie encoded with H.264 in a .mkv container without loosing frames. Does anyone know of any good mkv players that can reproduce high def video without dropping frames?
