8.2.1.3: Error reading blu ray disc

[lenkiatleong]

Hi,
I'm using DVDFab bluray copy 8.2.1.3. During copying process, an error window pop out saying error reading disc. Do you want to retry, abort, ignore or ignore all.
I encountered above error for below bluray disc:
1) Iron Man 2
2) In Time
3) Die Hard - Live Free

Please note that i had clean the disc and optical drive but error persist at the exact same time lapsed, e.g., when i copy Die Hard, error pop out at 62.17% and i got this twice.For other discs, it would be at other % point.
I suspect its the disc but when i inspected them visually, there is no scratch at all.
What must i do? Please help.

P.S.
I have no problem copying many other blu ray discs except those 3 above.

Sounds like you have a scratch or a defect in your originals....

Or it could be a manufacturing defect not visible to the eye and ignored by a set top player. Take them back to the store and trade for another if possible.
