Blu-ray will not play

I just bought and installed a Pioneer Blu-Ray DVD Writer in my computer.
Pioneer BDC-207DBK
When I try to play it I get the following message:
"Windows Media Player cannot play the DVD. The disc was created in a manner that the Player does not support."
Can anyone tell me what to do to be able to play my Blu-rays?
It will play a DVD and a Burned DVD, but not a Blu_Ray.
Please help.
Thank you

 

Windows Media Player does NOT play blu rays. You will need a player that does. I use TotalMedia Theatre 3 (for example). There are others available.

 

Thank you for your help. It was suggested that I get Cyberlink Power DVD.
I installed it and it works great.
Thank you again..

 

Glad you had success. There are many available programs.

 

thank god someone recommended powerdvd win dvd sucks

 

Are there any good free BlueRay players out there?

 

I checked out the home page, not free but it did look interesting, thanks.
