Hi... Was hoping for a bit of guidance please. I'm looking to add a Blu-Ray drive to my system, simply to play films on my PC. I've heard that not all Blu-Ray drives actually do this, and that some drives are purely just for data storage and access etc. Can anyone recommend a drive, and explain how i avoid buying one that doesn't actually play films. I know this sounds daft, but the last thing i want to do is buy one that won't do i what i want. Thanks in advance. Dave.
