I'm new to posting so please forgive any rookie mistakes. I recently purchased CloneBD and converted a couple of blu ray movies to MKV files. After the conversion I burned them to disc using ConvertXtoVideo. Everything came out well with one exception. The audio and video are in sync throughout the movie, but when a song plays during the movie, it plays at the correct tempo, slows down and then plays at the correct tempo again. Over and over... Very weird. Any suggestions?
