I have a MacPro 1,1 and thought I would need to upgrade the graphics card to be able to play blu-ray movies. I have a Sony blu-ray burner in the lower optical bay. Yesterday I installed makeMKV and the latest VLC. Archived a blu-ray, opened VLC and the movie played just fine on my 30 in cinema display. For a long time I had heard that Macs do not do blu-ray. But mine does. Whoopie! Now I can do my own blu-ray movies in FCS and play them with VLC. No need for the ATI 5770 after all.
