Plextor firmware\copy protection

[Weezel]

I have a Plextor 12\10\32 TA burner and I am using the original firmware that it was shipped with. My question is that a friend of mine told me that if I upgrade my firmware on my burner I would not be able to make back ups of copy protected cd's. Is this true? Does an upgraded version of firmware for the plextor 12\10\32 TA prevent me from making back ups of copy protected cd's? Thanks for any advice!
