Here’s my suggestion for those who want to play Region A blu-ray discs on Region B/ C BD players: Use Blu-Ray Ripper to rip commercial blu-ray discs to hard drive, connect the hard drive with BD player, and play the blu-ray movie from hard drive. Blu-ray players usually support various video and audio codec, and ensure high-quality playback of M2TS, MP4, AVI, MKV, MOV, etc.
