Hello,
I'm a french user of ImgBurn and I've same problem with Sony's media. I use a LG BE06LU10 with the last firmware (YE05) for this test.
I use Sony BD-RE 50Gb with ID MEI-T01-001 and I have problem to burn Blu-Ray movies. Yet, on another disc (same brand, same id) I've no problem.
After watching the disc data given by ImgBurn, the only difference between a disc that works and one that doesn't work is "Disc Definition Structure". For a disc that doesn't work, it's indicates "Certified: Partially (In Progress - Full) (LVAP: 1048576". A disc that works, status is "Certified: Yes - Full".
I test to erase disc and I obtain "Potential 'WaitImmediateIO' Deferred Error - (99%, 0/4) - Format Command Failed" close to 100% (maybe 99%) like if he couldn't close a disc.
Is there a solution to my problem? I hope I was clear but I remain at your disposal for further information.
Thank you.
Sorry for my english
