Problem with Pioneer BDR-203 Would not write TDK BD50 RE cannot read some Blu rays..

Hi guys,

I had this problem from the beginning and initially thought it is a problem of the disks or format itself is a bit raw but now starting having concerns that it might be problem with the drive itself… When I try and burn TDK BD50 RE it will write it ok until it came to synchronizing cash. At this point it will just stop and will not proceed any further. If I kill Image burn application using task manager I still can not get drive to open. I have to switch my pc completely in order to get my disk back. The disk will actually play in my Panasonic BD35 but I believe that cannot be considered a successful write…

I wonder if any one had problem with reading back Blu ray disk s you have written with this drive. I have written about 30+ Blu ray with this drive. They burned and verified successfully using Image burn. But few weeks later I have tried to copy back and about 30% of the disks I have written this drive cannot read back it will try to read them and will give up after few minutes saying no disk. The disks play OK on my Panasonic BD35.
I have only used Verbatim and TDK media made in Japan.
I have 1.10 firmware on it.

Did any one experienced any of these problems? Could it be faulty drive?

Any thoughts and advice would be appreciated.
Thank you
