Question

dvd shrink and dvdfab decrypter any one successful copying any of these

Answer 1

you need a better system of copying or just buy the movies.

Answer 2

cyclic redundancy check

A method to detect and correct errors by adding bits derived from a block or string of bits to the block. (2) An algorithm to compute bits characteristic of a block based on the algebra of polynomials over the integers, modulo 2. (3) The characteristic bits of a block.

is a type of hash function used to produce a checksum – a small, fixed number of bits – against a block of data, such as a packet of network traffic or a block of a computer file. The checksum is used to detect errors after transmission or storage. A CRC is computed and appended before transmission or storage, and verified afterwards by the recipient to confirm that no changes occurred on transit. CRCs are popular because they are simple to implement in binary hardware, are easy to analyze mathematically, and are particularly good at detecting common errors caused by noise in transmission channels.

i assume that the 2 movie cds are not properly burn or maybe over copied try to check if they have some scratches.
