I am looking into buying a Blu Ray drive for my desktop, and I have a couple things I want to know first, but am having trouble finding out. First, does a Blu Ray drive also read/write DVDs and CDs, like a DVD drive works with CDs as well? Second, while looking around the internet, I see a lot of talk about the hardware needing to be HDCP compliant. How do I know if my monitor and my graphics card are compliant? I have an Acer P215H monitor currently using a DVI connection and an AMD Radeon HD 6770 graphics card. Any help would be appreciated!
