Blu-Ray Version of USB Superdrive?

I'm looking for a Blu-ray optical drive for my brothers iMac. He wants to watch blu-ray films whilst being able to also have a drive that can read his game discs. The USB superdrive from Apple is pretty much what he is looking for - minus the Blu-ray capabilities. Do any of you know any optical drive devices that can act as both player and reader. I've been having a look at some Samsung models, in particular the Samsung 506BB, but they don't seem to play movies.

Thanks for your help!
