Media Server Confusion

I am thinking of getting a media server. I want to use it for movies and music. Can I record DVDs and CDs directly onto them? What things are important and what are not? I have an OPPO 95 and will most likely use Digital out from the server to the DA conversion of the OPPO. I would like to record blue ray DVDs and SACDs to the unit.
Your help is greatly appreciated. PS My wife requires an easy to use unit.
Thanks
Greg
