I have a new Audio/Video out of sync problem. I converting several 23.81fps MKV. The compiled bluray video and audio is out of sync. Does anyone know why? I tried changing the fps to 23.976 using the transcoding feature in multiAVCHD but to no avail. My current solution is to reencode the videos to new MKV/MP4 using MeGUI and then use multiAVCHD to compiled into bluray.
