He recommended BD Rebuilder. It's a nice soft, but it has a problem. It recompresses the video. No matter what you do. It allows you to leave audio tracks intact, but there's recompression with the video ones.
Not true at all! you are not setting it correctly, but it is to bad you guys have to do this to begin with lol, go into the settings and check custom size and then set it to a 50 GB BD, simple.
