For the 27-inch iMac I would like to be able to watch my Blu-ray discs on it and possibly burn the disc so I can include footage in my YouTube film reviews (that part is still up in the air for me since I don't know what kind of copyright infringements I could possibly get). Since the Apple USB SuperDrive only does DVDs, I'm looking for both a Blu-ray USB optical drive and the software to properly play the discs. Any recommendations?
