So, I want to start buying BluRay movies since they are good quality. So, I intend to rip them onto my Mac and pop them on my Apple TV. Now, I know my Mac doesn't support BluRay, but, to what extent? Can I buy an external BluRay reader and rip the disc in and play it? Or can OS X (10.6) not play BluRay movies either? And, when I drag the movie into iTunes, when streaming to my first gen Apple TV, will it automatically downsize it to 720p? Can anyone fill me in? Thanks.
