Page 1 of Skipping on Samsung 811

I recently swapped my Wharfedale 750 for a Samsung 811. While I have found the player performs really well, I noticed some skipping occured on certain discs. In extreme cases (Galaxy Quest) the film became unwatchable after the layer change and American Beauty would not operate from the menu system until I had forced the player to play some of the special features.
I have now fixed this problem, by moving my player. The Wharefdale used to be in a stack with my On Digital and Sky digital boxes sat on top of it. It did not have any problems, (apart from the well documented faults) however placing the Samsung in the same position caused the skipping. I now have the player on it`s own, and the player feels much cooler and no skipping has occured since.
