I cannot play Blu-ray Disc movies with CyberLink PowerDVD. What can I do?
By default CyberLink PowerDVD supports Blu-ray playback, buy if it's not working for you then it's possible you're using an older version of the software.
In case the software's still installed on your PC, access the link posted below and download the patches. This will increase compatibility with Blu-ray discs (Blu-ray DVDROM required) or enable playback of those files.
