Using DVD Shrink 3.2 and tring to copy Apollo 13, I can not get past the copy protection during the first analysing phase, at first I was getting a copy protection error but now I am getting a cyclic redundancy error. I have tried to use DVD Decyrptor but it never makes it through the decrypting process. Actually I have trouble using DVD Dycryptor. Any suggestions.
The "CRC" error invariably means a dirty, scratched or "just plain bad" source disc.
Try cleaning the disc. If that doesn't solve the problem, return it to the retailer if possible and exchange it for a new one.
I've had luck in some cases using Decryptor for these bad discs. I get errors, but a copy can handle several hundred errors and only have a few seconds of distorted material. However, if the "read error" count tops the 1,000 mark, I typically give it up.
Set Decryptor to "brute force" mode in setup, and set "read retries" to zero, or it'll take forever.
As bruwery said, CRC is usually a dirty or scratched disc. However, There seems to be a growing trend to prevent DVD backup by using unreadable sectors or hard copy read errors. This will result in the copy protection error you mentioned.
There are however ways to circumvent this method.
One is to use a slower read, even at 1x, if your DVD-ROM drive won't do it, try using your burner to read it.
Another way is there are settings in decrypter to make your rip more aggressive. here are a few as posted by my good buddy Pete:
DVD Decrypter can handle even the toughest of encryptions - Don't ever give up on DVD Decrypter, try the following little "adjustments" -
Step 1. In DVD Decrypter, go to "Tools", "Settings", and then whatever you're using either the File Mode tab OR the ISO Read Mode tab and "tick" "Remove PUO's" - try either the IFO, BUP, PUO's OR the VOB PUO's
Step 2. In DVD Decrypter, go to "Tools", "Settings", General tab, on the bottom left it will say "Removal Method" choose "Aggressive".
Step 3. in DVD Decrypter, go to "Tools", "Settings" then choose the CSS tab, under CSS Cracking Method, mark the spot that says "Brute Force -> I/O Exchange".
Finally AnyDvd has a new setting called "copy protection based on unreadable sectors", check this box when encountering such errors. AnyDvd has a free 21 day trial, then it costs 39.00. It is well worth the price as it runs in the background completely on automatic with nothing to operate. It also works for burning on the fly without writing to the HD 1st..
Use any or all or a combination of these means will usually get around the problem, good luck.....:>).
