[Optical Storage] How to fix specific media players cannot play Blu-ray Disc?

If you use specific media players to play Blu-ray disc, there will be a pop message "This Blu-ray Disc needs a library for AACS decoding". It represents that your optical drive has detected Blu-ray Disc successfully. However, the disc is encrypted by AACS, and you have to download or purchase a media player which supports AACS decoding (e.g. Power DVD) to play Blu-ray Disc.
