thanks @yesyes and @vx2 for the inputs...turned off trumotion and so far ok...
another question, when i change channels, normally there is a black screen in between. on this black screen, i see light horizontal bars going up or down...is this normal or is it supposed to be totally black? this horizontal bar moving is also sightly seen when the channel picture is being shown already...
(to better understand what i am saying, when you watch a movie and in the scene there is a computer, you can see horizontal movement on the computer...i don't know what this "phenomenon" is called...)
i don't notice this when watching dvd movies...is this because of the cable connection? i am a sky subscriber...
sorry if i'm being paranoid...i'm just being OC within the 7-day warranty (replacement) period...
