Hi Guys, I have three questions: I have the first run Power Mac G5 from two years ago. I think it came with a 1X dvd writer and I was able to upgrade the firmware to 2x ( I kinda remember doing that). I notice it will not accept more recently purchaced media at 16x speed. My questions are... -How do I verify the speed it will write at? -Can I make it write even faster? -Do I have to use only 1x or 2x media? This is not as available anymore. Thanks in advance.
