clone Cd & LG8080B

I recently downloaded a copy of clone CD to try with a LG8080B burner (so I could make a back up copy of PSX Sydney 2000 australian version.). Initially it appeared to be compatible. I can quick erase CD-RWs. I can burn audio CDs. When I try to burn Sydney 2000, it make a copy of identical size to the original, but the copy fails at the protection stage the same as when I use CDRwin. Is this because the LG8080B is not 100% compatible or is it a problem with setting etc.
