I have been using my GSA-4163B faultlessly for a long time now.
Recently I bought a DVD and went to play it, only to find it wouldn't - the disc is not recognised, and if I go to My Computer, the drive renames itself to "CD Drive" and if I open it, shows an empty CD with XP giving me the option to "burn files to this drive."
This DVD has since been tried in other DVD players and works fine.
All other DVDs were still being read, then another new had exactly the same problem - not being recognised at all.
This problem occurs all the time with affected DVDs, but NEVER with ones that have and always have worked. I tried cleaning the lens anyway, but the problem persists. I have tried flashing the drive to the latest firmware, but it performs in exactly the same way. I have tried uninstalling and re-installing the drive but again - to no avail.
Does anybody know what could be wrong? The flashing etc went fine, nothing changes though.
