Error correction comparison
For this test a recorded DVD which we had problems reading past the final
chapter on the main movie on a standalone player was put through each of the
software listed in the below table.
This was due to misuse and a scratch had
appeared across the disc. The purpose of this test is to see if any of the
software can recover the bad sectors and enable us to once again have a
good working backup of our DVD Video
As you can quite clearly see, there is only one winner in this
comparison. Only one software managed to successfully read and correct the bad
sectors present on this DVD, giving us the ability to back up what appeared to
be a very troublesome DVD Video for all the other tested software.
| Software Tested |
Able to read and repair
bad sectors |
|
1Click DVD Copy |
yes, after 10 minutes the bad sectors were corrected |
|
Clone DVD |
Failed to read past bad sectors |
|
DVD Fab |

|
DVD Cloner |

|
DVD Shrink |

|
DVD Decrypter |

We must stress that it is very often the case that even the best error correction cannot recover extreme cases of data corruption, but the DVD VIDEO we tried certainly played back fine without any video glitches being noticed at all.
