Just an update...
I ended up buying the drive and have had zero success. I had many issues getting the included software to work. I installed it, then it said it needed to update right away in order to play the disc (any disc I tried), but the update installer would give an error. Then trying to uninstall the software gave me the same error, making it very difficult to uninstall. I emailed back and forth with tech support for about a week and finally got the latest software to work, but then whenever I went to play a blu-ray I only got audio and no video (just a black screen). Since my x1600 isn't technically supported in Windows 7, I went back to a fresh install (with all the updates) of Windows Vista and still had the same problem. At that point CyberLink told me to consult my manufacturer, which leaves me at a dead end (Windows 7 + 1st Gen MacBook Pro + Apple + blu-ray = good luck). I've already filed for an RMA through NewEgg. I just thought I would give everybody a heads up before considering buying this for their MacBook Pro.
