When I play a video on my macbook I get a much better picture than playing it on the mini, I dont understand. I use a samsung le32r88bd with my mini and when i play xvid movie the picture looks different. Could it be the size of screen making the difference. Its a bit jittery at times too. Both macs are 2ghz intel core 2 duos, I dont see why the macbook is giving better performance that a desktop basically.
