I have a BenQ DW1620 OEM(bulk version) which does not read some DVD’s. The strange thing is that my firmware version is G8C9 but other people with the same drive have a firmware version of G7P9. When i put the DVD in the drive, windows does not detect it. None of the programs detect the DVD. When i put in another DVD it works, so it’s not a problem with my DVD drive. The DVD works on my DVD player but it doesn’t show up on my computer. Can someone help me with this problem? Thanks!
I think it’s a (usual appearing) software conflict.
Please look into the Benq subsection.
