Ps3 wont load some bluray movies (sometimes)?

I have the ps3 slim 250gb. It has the latest firmware. My bluray disks are clean as a whistle. My ps3 never has any issues playing games or dvds or cd's. The problem is that most of the time it wont play bluray movies. It currently will play imax under the sea in 3d though. I just bought rise of the planet of the apes and the minute i pop it in this is what happens just like most of the other ones. I insert the disk and I hear a clicking sound (about two a second) and the disk spinning in the top right of the screen. Then it makes a fake eject sound but the disk does not pop out. Never does it show up on the menu to play. Now a couple of weeks ago I had about a week and a half straight with no problems. Now that it started back again im upset. I know it has to be a firmware problem because games are on bluray disks also. Its not the laser or a scratched disk. Its not region code problem, nobody seems to know. Other people on the internet are having the same problem if you google (ps3 wont play bluray) you will find many other cases of this as I described. If anyone has an answer that would be fantastic so that i dont have to spend 150 dollars sending it to playstation. I will be reposting this elsewere.
