These are a few reasons why you shouldn’t use your PS3 as a Blu-Ray player.

• Doesn’t work with Universal Remotes
• Louder than Standalone Blu-Ray Players
• Interface is not user friendly
• Doesn’t work with multichannel analog outputs of any old AV receiver
• Consumes a lot of power
• Doesn’t integrate with new AV recievers to say that it is producing DTS-HD and Dolby TrueHD sound.

I have tried the PS3 as a Blu-Ray player and I have found it to be a bit stiff, and its annoying using the controller to control the whole thing, it doesn’t have IR so you can’t control it with another controller. The interface has a lot of features but it does take you some time to figure out the menu system.
