LG-Super Multi Blue BluRay Disc Rewriter BE12LU30
Magix Edit Pro 17 HD+ Video Editing Software
I've created a movie, it works fine start to finish while running within Magix software. All copies of BluRay Discs burned have same audio/video sync problem. About a 1 second sync error by end of 30 minute movie. Starts out in sync, then progressively noticeable after about 10-15 minutes into it. Any fix? I've tried multiple format and encoding changes, nothing helps. MPEG2, MPEG-4, AVCHD....
