Have you tried changing the output signal from the Blu-Ray player? In the U.S., changing from 24Hz mode to 60Hz mode can sometimes alleviate this, but I'm not sure how that translates to the signal in your region.
I have a samsung LED TV (UE37C6500) which suffers from an inytermittent judder whenever I watch Blu Ray content either through my PS? or Samsung Blu Ray player (BD-C5500).
Is this a common fault and if so, is it fixable?
