1. You wrote "my blu ray movies" so if they are indeed yours that you created why not use the source content instead of the BD media?
2. So far all BD is copy protected and these forums don't discuss ripping of said content. That's so you know how to avoid this discussion getting locked.
3. Some BD's that you purchase have "digital copy" features. Use that and you're done.
4. Yes, you'll have to get a blu ray drive for your iMac to do item 3.
Again, if you want to rip BD today, wrong forum.

I want to be able to burn my blu ray movies to my hard drive in a format that can be stored/accessed by my PS3 player so I'm not constantly fumbling through disks to find the movie I want to see. Is there a way to do that? Do I need to get an external blu ray drive to plug into my iMac to do this?
Thanks!
