For those of you who are having trouble getting your blu ray discs working in your BD drive, I just went through a 5 hour ordeal of testing and troubleshooting before I was able to get mine to work properly. I picked up an internal BD combo drive off newegg, LG UH10LS20 OEM for $35. Installed the SATA drive in desktop running Windows 7 Ultimate 64-bit. Windows automatically installed all drivers. I purchased the region free BD disc "Hancock" and the drive was able to recognize it as a BD disc and showed the name Hancock. The BD player came with Cyberlink PowerDVD 9 Ultra which supposedly supports BD content. When I loaded Hancock the player would pop up the message similar to "unsupported format in drive". This is where my problems started, and I am going to skip a bunch and go straight to the solution. 1. What you need to do is first make sure you have the lastest firmware running on your BD drive, which consists of going to your manufacturers website and typing in the model. Older firmware versions can not support all current BD discs. 2. I had no luck with PowerDVD 9 so I picked up PowerDVD 10 Ultra 3D. The default region code setting for this software is region free, I set mine to region 1 (USA). 3. Now you need to set the region code on your BD drive. Click Start Menu and in the search bar type "Device Manager" and open it. Locate your BD Drive and open it. Select the Region tab and select your region, mine again being region 1 (USA). 4. Next to ensure you can play ever BD disc you own you are going to need a program by SlySoft called AnyDVD HD. This program removes any security that may fight against PowerDVD and also allows BD discs with additional content like games or BD/DVD combo discs to be played. 5. At this point you may still not be able to play BD discs through PowerDVD and may still be getting the same "unsupported format in drive" message. If this is the case you need to open your device manager again and uninstall your BD drive. Restart the computer and allow Windows 7 to reinstall the drivers for you. 6. At this point all BD discs should be working. Enjoy the 5 hours of life I just saved you!
