DVR-103 and unrecoverable DVD-RW

I am using a Pioneer DVR-103 burner with the 2.00 firmware and I’m having strange issues.
All the DVD-RWs (TDK) that I’m burning with this drive can be read on other drives, but cannot be burned on my Sony DRU500A.

Today I also lost a DVD-RW for unknown reason. I cannot even erase it with Nero as it is giving read errors while erasing the media.

Is this a known issue? Is there any workaround or any way to recover the now bad media?
Thanks!
