試試看(321 Studios的)DVD X Rescue~~~我是沒用過(還沒需要)，不過，應該可以吧?!

DVD X Rescue is designed to recover movies from DVDs as well as recovering data from CDs and DVDs. There are several analysis tools which help in diagnosing problems with discs and for quality checking. Using this tool it is possible to recover data from most discs with inaccessible data.
