Lite-On LVW-5115GHC+ DVD Recorder

Hi everyone.
Is it possible to disabale the copy (Macrovision or whatever it is called) function of the Lite-On LVW-5115GHC+ DVD Recorder.
I want to copy some of my dvds and it won’t let me.
Also is it illegal to copy DVDS or not?
I have no problems transferring my DV and 8mm camcorder movies at all.
If anyone can help it would be appreciated, or direct me to someone, or someway of doing this.
Thanks

And ahve agreat new year everyone.
