The latest version has introduced terrible lyp-synch problems, for me anyway.
After DVD-Ranger cinexHD has done its job, I have to run the resulting video through MKVtoolNIX and set the audio between -300/500 delay to get the audio back in synch!
I was gonna asked on the official forums, but there are hardly any posts on there at all, so thought I could find an answer on here.
P.S. One other thing that baffles me. Why is there no pass-through option on the video side of things? After all, this tool is all about replacing the audio, so a direct copy of the video would speed things up considerably!
