Upon first try, didn’t work, it just froze, the same symptoms as “not responding” , but for some reason when trying to force quit it, it is not recognized under being that state… After force quitting, it would no longer open, and it would cause my computer to crash when shutting down… well i’ve deleted it from my hard drive. Most other bluray players are paid softwares , this one was free , so i thought i’d give it a shot. I then tried purchasing a 30$ software with the same symptoms.. i dont know if it’s my bluray player that’s not compatible, but you would expect the app to be compatible with all players… 3 stars, because it’s not just this app that’s having problems
