I'm looking to buy a fairly inexpensive blu-ray burner, such as this one: http://www.amazon.com/LG-GGW-H20L-S...1?ie=UTF8&s=electronics&qid=1222986777&sr=8-1 My first question is..Is this even going to work on my Mac Pro? I know about software requirements such as Toast, but are there any other limitations? Also, is it even "safe" to buy blu-ray yet? Is the format here to stay? Is it still growing enough to wait a year or two?
