My TS H552U DVD177RW Dual Layer Burner burns 80 percent then stops or gives me errors

Updates on dvdcopy software will cause you to not be able to copy dvd and game software rollback you software to the original drivers and you should be able to copy the disk with out error .errors accure when you have dirty lens or dirty software or you are trying to copy illeagal software which is a big nono ...if you have a disk that is damaged the manufacuture will replace it with the cost of shipping if you have registered it and that should solve you problem with the disk. most errors that happen are because disk are copywrited and on game there is a yellow security code in the disk that keep you from copying them .Use a dvd disk cleaner to clean you lens and any copy errors should be gone and make sure that there are no prints of smudges on the disk that you are trying to copy .good luck
