I just recently got around to installing my blu-ray drive in my pc slight problem, nothing i use will play blu-ray it's an unsupported format basically, avg says it plays blu-ray but still tells me no, what application is used for blu-ray.
Been in that scenario a few years ago, and it's easier to just get a Blu Ray player and hooking up to a TV. VLC can play after some additional fiddling; not ideal but better than nothing. (Google is our friend here.)
However, some drives may have included software for Blu Ray playback. Otherwise it will require purchasing software which is tailored towards Blu Ray disc playback.
