all profiles in copy and ripper mode and it does not matter which of my 3 computers i use to copy the disc. Different copies of the same movie using different discs produce the same result
it is only on some movies. and the out of sync is progressive, that is, it gets worse at the same rate as the movie gets closer to the end.
if a constant frame rate can be achieved on the host computer ( i realize this would slow the copy process considerably) using a selectable setting then it can be applied to the troublesome movies with pedantic precision
