Burned the disc twice successfully and tested on 2 different Blu-ray players including Panasonic and SONY Blu-ray player. And very beautiful and expensive versions. The hard drive didn't work. We burned the same ISO file onto a regular (non-rewritable) disc and it worked fine. I read some reviews that said it was defective, but I assumed people use cheap Blu-ray players that often can't read recorded media. But no, our glories don't read this disc either. Before that we had a Verbatim brand BD-RE and had no problems.
