For some reason my Blu-ray player has stopped playing blu-rays, but plays DVDs just fine. It used to play blu-rays, although getting it to play when I first got it was a pain and I can't remember how I solved it. I have recently upgraded my graphics card, ATI 4750x2 to NVIDIA 560Ti. Anyway, as far as I know my computer meets all blu-ray requirements, as I've played them before. I use PowerDVD 10, upgraded for free from PowerDVD 8 which came with the drive. Cyberlink's BD Advisor shows that everything on my computer meets blu-ray playback requirements, except for the blu-ray drive. So that to me is the problem. I know windows 7 doesn't have blu-ray functionality but I thought software like PowerDVD was supposed to take care of that. So I tried installing the firmware for my drive from LG but the installer says it can't find the target drive, and LG's automatic firmware updater shows no blu-ray drive either. LG's customer support was no help, nor was Cyberlink's. Usually when I've had an issue I found others with a similar problem but not this time it seems. While there are lots of results for no blu-ray playback non have helped me. So I've turned to here for any answers. So, how do I install firmware for a drive the installer says doesn't exist? If that's what will solve my problem. Can anyone help? Thank you.
