Pioneer BDR-UD03/UD04 has reading problems with a specific Blu-ray
Posted: Tue Mar 17, 2026 2:40 pm
Hallo,
I have a Pioneer BDR-UD03 drive, that is crossflashed to BDR-UD04. Firmware: 1.14. MFD: 2015
This drive has a strange issue. It works fine with all my BDs und UHD BDs, but I have a quite new BD that this drive only now and then can read. I have two newer Pioneer BDR-UD03 also crossflashed to BDR-UD04, same firmware. These two drives can read this BD without problems.
I have already cleaned the lense with alcohol. I have tried different external cases. I have tried the drive internal. No success. This drive can't read the one BD steadily.
Any ideas?
Thanks!
