Last night I installed an LG BluRay internal drive in my Mac Pro - 30 minute install. After reboot the drive was identified right away and I prepared to do testing with Blu Ray Rips to backup my BluRay of Transformers. (I) I first used BlueRayRipper for Mac - very poor software, I highly suggest avoiding it. The audio was totally out of sync with the video, not even viewable. I then used MakeMkv for Mac - intuitive and fast Utilized Handbrake to encode as an MP4 full 1080p. It took a *long* time but the video quality is excellent. The only issue I have is the audio is cutting out 50% through the entire movie. For purposes of troubleshooting can someone recommend a 'player' for MKV files to determine if my source is faulty or provide suggestions on what I may be missing on the audio settings in Handbrake? Thanks!
