Do standalone dvd recorders encode a light encryption?

[yoda313]

Hello,
I was wondering something after I ripped a homemade dvd from a settop dvd recorder. A friend gave me a backup of an old tv show (not available commercially) and I ripped it using dvd decrypter. It actually showed it using an encryption, lba something (sorry I can't remember the number sequence).
This is odd. I thought personal backups were completely unencrypted. I know you should be able to rerecord them to video (ie no macrovision).
If anyone has experience with this I would like to know.

By the way, the disc copied fine and I used it for editing purposes .
Just curious about the encryption.

The encryption that DVD Decryptor is breaking is the CSS encryption. The CSS encryption prevents you from copying the DVD video files from a DVD directly to a computer. Macrovision prevents you from copying to a VHS video tape. Basically, Macrovision prevents analog copies and CSS prevents digital copies. My guess is the maker of your DVD recorder doesn't want you to edit the files on your computer, and so uses CSS encryption to prevent the average user from being able to doing anything but watch the DVD on the computer.

DVD recorders do not add CSS encryption to their recordings. It is not possible because the area of a DVD that is reserved for the CSS key is not writeable on any recordable DVD media and even if it was, burners are designed to not write to that area anyway. Most likley what DVD decrypter saw was some bad sector that caused it to think some encryption was present even when it was not and the DVD rom drives error correction mechanism enabled it to read the bad data correctly.
