You do face problems some times in ripping DVD as getting errors like "Unrecovered Read Error" or "Data cannot be read" etc. Read errors on a DVD are sometimes caused by scratches; sometimes are inserted in DVDs to inhibit people from copying them, better known as DVD copy protection. Scratches on a DVD can often be fixed by using rubbing alcohol, furniture polish or toothpaste to remove scratches and smudges from a DVD's surface. After these imperfections are removed, the DVD should perform much better in your DVD ripping program.
But to copy protected DVDs is really a big headache. This is because companies making DVD movies make their DVD in such a way that if you ever want to copy it, your DVD ROM will get stuck in a particular area of the DVD which it wont be able to read and therefore gives a DVD read error. Most DVD uses a copy-prevention algorithm such as Content Scramble System (CSS), Region Code Enhanced (RCE), User Operation Prohibition (UOP), Sony ARccOS DVD protection, the Analog Protection System, etc. which helps to prevent DVD movies play in a region before a film is released in theaters.
