scratches and Blu-ray Disc

[caparazon]

They say blu ray discs protective coating is stronger than DVD, but the first blue ray disc I have ever used got a scratch!.
I haven't got any copy of the archive recorded on it, -an .avi moovie-.

Even though Win DVD can read and play the film, the fact is that when it reaches the damaged sectors, I must quickly jump over these damaged sectors using the player's sliding control, otherwise it keeps skiping and the player gets blocked. Then, if I succeded in this operation I can still play the disc second part after the scratch until the end of it.
Does anyone know about any program that could extract and make a repaired copy of the entire non-damaged sections of the film?
