Downloaded from the Lite-on site, the file is called MS0P.exe, it automatically updates the firmware and leaves no details behind so I'm not exactly sure what it's been doing or if there's even an uninstall option at all.
I'm using primarily DVDFab decryptor and DVD Shrink and also Nero.
This is the latest and only firmware available for my DVD drive on the Lite-On site, so as far as I can tell I'm not missing anything because I searched that site quite a few times.
I'm referring here to the new firmware that I'm having problems with (MS0P).
As for the older firmware versions, I got them all from Softpedia
. I also downloaded and tried the same versions again from some Chinese website just to make sure.
