Plextor External DVD Drive Problems



I was wondering how the heck do I get the Plextor External DVD drive to burn stuff in itunes and disk ulity?? Because I have the latest firmware for it. I'm running 10.4.1. Doesn't make any sense to me at all. It says in system profiler that it's not supported by apple. Does this mean I can't get it sopprted so that it will burn in itunes and any apple app that requires dvd burning? I'm using a Plextor PX-716 UF. It the latest for the company. Thanks for your time. :D
