Well, I would disagree there. I can launch my Blu-rays through the default movie library as is using TMT5. My issue with the default movie library is that it just presents everything individually. That's fine if you only have a few dozen movies, but when you get in the hundreds, it becomes a pain. In MB, it recognizes folders, so for instance, all my Star Wars movies are in a folder. When I click on the Star Wars folder in MB, it opens up to show me all 6 movies. That kind of organization makes navigating a large library navigatable IMO. Plus I prefer the cover flow view.
