I don't have a BR drive in my
PC so my experience is limited in this arena, but my understanding is VLC has some support and will play back BD discs.
Go to
this url.
1.) Download and install the VLC player from the very first link on the page. This should work for non-encrypted discs.
2.) Otherwise, get the other 2 links and follow the directions on the page. Should only take a few minutes and no reboot.
