FSET642 has advertisements at the beginning and end of the video, but not the usual shrill Chinese lady screaming. And, thankfully it isn't watermarked. But for sure the addition of the ads probably messed up the sych totally. The Chinese ads for sure mess up the sync by about 1 second on nearly every video I've checked.
Let me know if you want me to post my "fixed" version of FSET642. It's close but not perfect. For sure it is watchable unlike the original version. I cut off the ads and the previews at the end, so just the movie.
