Since my new computer didn't come with a blu-ray player, I quickly voided the warranty and yanked the blu-ray from the old machine and installed it in the new machine. Win8 still doesn't support blu-ray, but I had Cyberlink Powerdvd10 on the machine from the manufacturer. Unfortunately, not all versions of Powerdvd10 handle blu-ray. I purchased and downloaded Cyberlink Powerdvd12.
What the heck? After installing it, the computer no longer showed either the original dvd drive player or the blu-ray drive. Also, neither drive would work. I could put a disc in and hear it spinning, but nothing would happen. I fiddled around with it off and on for two days and nothing worked. I finally managed to find someplace in Win8 (can't recall how I got there) where it told me the drivers for both disc drives were corrupt. I re-installed the drives, and still no luck, the drives wouldn't work.
I un-installed Powerdvd12 and they still didn't work. Re-installed the drivers again, and still they didn't work. AAARRHHGGG!! How frustrating. Finally, I did a system restore back to the point before I had installed Powerdvd12. Presto magico, the computer now recognized the drives and they worked. But...... the blu-ray capability was not there.
Now that everything was working again, I established a new system restore point. I re-installed Powerdvd12. Everything worked, computer sees the disc drives and a blu-ray movie will play.

I am happy again.
So, my advice is this.......
If you have a blu-ray drive and you want to install Cyberlink Powerdvd12, before installing it, set a system restore point. If it corrupts your disc drive drivers, go back to your system restore point and then try again.
Oh, by the way, whilst putting in the blu-ray drive I also installed 4 additional gigs of RAM (old machine to new machine, same RAM) for a total of 12 gigs RAM and I put the old SATA drive into the new machine. Total storage is now 2 terabytes.
