I have movies I ripped to my drive using CloneDVD (the x studios one). Anyway, it claims to remove the UOPs, but when I burned to my dvd+r's, they were still there. However, when burning to my dvd-r's, they are in fact gone. Again, same movie files, simply burning with IMGBurn to a dvd+r and then a dvd-r to compare. Can anyone explain this?
