I recently purchased a PS3 for my first adventure into Blu-Ray. I have the PS3 hooked up to my Sony receiver model STR-DE885 via the optical audio connection. Whenever I try to run a Blu-Ray movie through my surround sound the sound cuts in and out. It acts like it looses the signal all together. I first thought bad cable but it's fiber.....it either works or it doesn't.

Is the PS3 putting out more sound than my receiver can handle?

Anything else I should check?

Help!! I want to hear that new THX surround sound demo at the beginning of Indiana Jones through my surround sound!!!

I believe your receiver is one of the "defective" models that is unable to handle the 640Kbps Dolby Digital bitrate. This happens with some older receivers. Your options are to (a) use 2-channel analog out from the PS3 with ProLogic II decoding in your receiver, or (b) buy a new receiver.

That's kind of what I thought. My question is that why doesn't it do it when I am playing a video game through my surround sound? Different output? Thanks for the response.

I'm not very knowledgeable about video games. But I'd guess that the game is either outputting a lower-bitrate Dolby Digital signal (448Kbps or less) or DTS, or a 2-channel PCM signal that your receiver is converting to multi-channel via Dolby ProLogic II.
