The narrow-guage laser of a BD-ROM drive is your friend here.
Might get lucky and read the entire disc without errors (but could you trust the results?)

A better option might be finding two bad copies of the same title.
Might get lucky and the bad sectors from each copy might not overlap.
That is, assemble a good copy from more than one source.

Don't ditch the rotters!

This reminds me of something Russs mentioned to me recently.
Russs probably thinks I'm an asss for never acknowledging the PM he sent last month, but honestly I never could decide how I wanted to respond.
Reluctant to accept the nomination to become 'data recovery guy' . . . yet somehow unable to say no. A peculiar form of 'preservation' but somehow tempting.
How about it Russs? Got a bad copy of DJ_SWE_Ep6 ?

skyjedi2005, got a copy of DJ_SWE_Ep6 ? I'll trade you DJ_SEW_Ep4_ISR for it.

I got the skillz to try it but there's just one problem -- I ain't got no BD-ROM.
Might get lucky trying several different CD burners...
