After updating my 2012 MacBook Pro 15" to Yosemite, my downloaded video files have trouble staying A/V synced. Every 10 minutes or so, there's a skip and the sync is broken. I can realign it by reviewing the video 10-15 seconds.
This happens regardless of video player or video file type. At first, I thought it was VLC and I tinkered with it's settings, which did not change anything.
Later, I realized it goes across programs (VLC, QT, MPEG Slipstream, MPlayer Extended OS) and file types (mp4, mkv, etc.)
I can play them on my other laptop (Macbook Air 2013 13") with no problem. Same files, same programs.
Any ideas what's wrong with my MBP?
Thanks!
