GRC

So I have tried a £4 VERBATIM that has worked ok. I am still left asking the same question...why do the MIRRORs suddenly not???

Looking at past logs the batch is the same code.

2x produces the same veryfying error about halfway through.

I am clueless as to why my 1st set of 10 MIRROR BD-R discs were all successful, whereas the 1st 3 of a new batch have failed to verify? I have not changed anything of my setup...is it just a case of bad media?
