PS3 odd problem trying to play The Descent

[Amon37]

I rented The Descent from blockbuster. When I put it in the PS3 the system would not recognize the disc. I shut the PS3 off and turned it back on and still no movie to start. I check the disc and it was flawless.

The way I had to get it to play was to turn the auto-start disc function back on and the reset the PS3, at that point it showed the disc and then automatically started up. The movie played fine the whole way through. I just thought it was weird I have never had to start any blu-ray like that.
