LG DRD-8160B firmware 1.01 problem



I have an LG DRD-8160B DVD-Rom.
I upgaded is firmware to 1.01
The operation successfully finished but now I have many problems…
1.) Reads DVD slow… The result of this action is a freezing on my screen as the movie play
2.) Reads audioCD with problems. As a track is playing might pause for a while…
3.) Can recognise discs at once. I have to eject the disc and reinsert it. (This is not happening every time I insert a disc)
I have to say that the problem can’t be a fault of my SoundBlaster or my Graphic card (as my CD-RW plays everything right)
What can I do?
LG servise don’t help much
