First of all this is a retail boxed item. You get the drive and Cyberlink High Def Suite software which will allows you to play HD films (nice). I am no expert, but here is my experience so far:
Be aware that your PC hardware specification should be quite high. Minimum recommendations are:
CPU : Pentium D 3.2 GHz
RAM : 1 GB
The most important issue is with the graphics card. It must be quite new, therefore, have HDCP support. I think this relates to the region system. And with Nvidia cards, you have to have Purevideo software (not in the package).
My XFX 7600 GT SLI graphics was the component stopping my installation. It had no HDCP support (according to the advisory software that comes in the package). I am waiting for a new card (Gainward 8 Series).
I am hoping that this resolves the problem. Hope that has been of some help. I will adjust my star rating if I get it working!!! : - ).
