I need help with weird LG 4163B

I need help with this LG with firmware version A105 (the firmware upgrade process occured sussesfully) showing a weird behavior: every time I use the Nero Info tool to see his specifications it come up with diferent and nonsense speed values and sometimes even 40x in all fields.
I’ve always been able to burn CD and DVD with no problems but lately some DVDs cannot be recognized.
Now I am just wondering to know what is going on with this burner.


I think you need to have a disc in the drive in order for Nero to properly register burn speeds. As to the un-readable discs, give us more info, such as the media code and where the disc is having problems.
