While I've always been a fan of itunes and media center (I'm sure that made some people reading this faint) I've recently had a large addition of avis and a couple other formats added to my library. As a result I can't use just itunes and I don't really care for the format of media center audio. So the question is, which software is the best at organization and playback. Pretty simply question I hope. Blu-Ray playback would be a plus.
