Brightness Fluctations on Playstation 3 Blu-ray Playback?

[DJCoyote]

I only have one BluRay player, and its my PS3. Its served very well so far.

I picked up Bolt on Blu-Ray today and im watching it right now. Im however noticing something extremely distracting: The brightness keeps fluctuating. pretty regularly throughout the film.
Its playing through an HDMI cable to 1080p RCA LCD TV.
Ive adjusted the AV settings around, switching between RGB and that oddly named setting (CMYK?) and automatic. Played around with the Super white, and all settings.
Nothing seems to solve this.
All connections are securely placed, all settings are optimal, and interestingly enough: the DVD version of this same package is not doing this.


is there a problem with the Blu-Ray version of this movie? or is there definitely something wrong with my playback? Any tips or pointers i can try to remedy this? Its EXTREMELY annoying..
