I just got a PS3 and still toying around with it. I got several blu-ray movies also!

Can a PS3 backup blu-ray movie? or do I need blu-ray pc drive? I'm planning to get one in the near future and looking around the net, I can handle the cost and I have plenty of time at the moment. I also have a new PC that is quite powerful.

My plan is to be able to play the backup in my PS3. Any advice much appreciated!
