Cyclic Redundancy error

[Movie_viewer1]

Hi, im trying to back up my copy of the Gandhi movie, but i get a cyclic redundancy error on shrink and decryptor.
Any ideas???

[anonymez]

it is quite likely that your dvd is damaged/scratched/dirty. try cleaning it.

A CRC (Cyclic Redundancy Check) error is DVD Shrink's and/or DVD Decrypter's way of telling you that it cannot read the disc (DVD). It is caused from the disc being to dirty (fingerprints, smudges, etc.) or being to scratched. First, try cleaning the DVD. You can try toothpaste to lessen the severity of the scratches. (By no means am I saying that you will totally restore the DVD back to original condition, all your doing is just trying to get DVD Shrink to successfully read it.) If DVD Shrink or DVD Decrypter still generates this error message, I suggest returning the original for a different copy.

I used a game doctor to try cleaning the DVD, but it didnt work. However, i am intrigued by the toothpaste technique, could you elaborate on it?

Also, here is my DVD Decryptor Log:

You can try toothpaste to lessen the severity of scratches.

Yep, just put a small dab directly onto the scratch, use the traditional white variety not the clear gel type. I then use a soft tissue wipe gently in only a radial direction (a straight line between the hub and the rim). Since the data is arranged circularly on the disc, the micro scratches you create when cleaning the disc (or the nasty gouge you make with the dirt you didn't see on your cleaning cloth) will cross more error correction blocks and be less likely to cause unrecoverable errors.

If you continue to have problems after cleaning the disc, you may need to attempt to repair one or more scratches. Sometimes even hairline scratches can cause errors if they just happen to cover an entire error correction (ECC) block. Examine the disc to find scratches, keeping in mind that the laser reads from the bottom.

There are essentially two methods of repairing scratches:


Fill or coat the scratch with an optical material.

Polish down the scratch.
There are many commercial products that do one or both of these, or you may wish to do it yourself with polishing compounds or toothpaste. The trick is to polish out the scratch without causing new ones. A mess of small polishing scratches may cause more damage than a big scratch. As with cleaning, polish only in the radial direction.

also, there is an option "ignore read errors" in dvd decrypter options (its in there somewhere, look for it) enable it, then try decrypting again.

i once had a very damaged dvd. it would not go past 42%. i enabled 'ignore read errors' , and eventually got it up to 43%, 44%, etc. (transfer takes much longer in damaged parts) once it got past the damaged part, it sped up and worked perfectly

[jmet]

Sometimes ignoring read errors can cause problems in DVD Shrink down the road.

[anonymez]

what sort of problems exactly?

i encoded to xvid instead of shrinking, and i guess i didn't notice anything wrong...

[jmet]

They can cause various error messages in DVD Shrink. Usually "Programming Errors" I think. Sometimes "Invalid data in VOB file" error message.

Update your firmware! Your 5 versions behind. You want to download "A209" - http://forum.rpc1.org/dl_firmware.php?download_id=1796

Your disc is either scratched or dirty. If dirty, clean first before trying to rip it. If scratched, you can try to lessen the severity of scratches by polishing them out with liquid car wax or toothpaste. If if it still fails, return it for a replacement.

"Would DVD43Free help me burn this movie?"

NO! I would stay away from DVD43. It can cause problems with DVD Decrypter!
