I got this for Christmas, and i must admit it is a wonderful piece of kit. Very solidly built, and a great idea!
However, there are two things to note about it.
1) You need to have a DIVx account set up (easy enough to register) and have some software installed on a PC in order to authorise the movie to play for the first time. After that, you can play it anywhere i think (i had it running on a laptop and a PS3)
2) The packaging says it's Dolby Digital audio, but it was only encoded in stereo. I have confirmed this with the DIVx helpdesk.
So all in all a fantastic way to view the new star trek movie, but bear in mind if you have a home cinema setup that the film isn't in 5.1 like the DVD/BlueRay.
