I am interested in buying a Bluray reader/writer for my Mac Pro and have a couple questions. 1. Is there any way for a Mac to play a Bluray movie directly from disc? 2. I would like to rip Blurays and also use the drive for creating backups of my photo library - both of these activities should be possible, correct? 3. What software is required for ripping Blurays? I have been using RipIt for DVDs...will it work for Blurays? For encoding, will Handbrake still work? 4. How much HDD space would a typical 2 hour long encoded bluray movie take up? 5. I already have an external FW800 DVD burner that I bought from OWC. I would like to purchase an internal bluray reader/writer and pop it into the enclosure. Will there be any major differences other than I/O speed when using an internal vs. external bluray drive? 6. Are there any known drive makes/models I should avoid? Thanks in advance!
