i never question that the world is perfect...when u said the video is smooth and run smoother w certain profile , i thought u meant every video is smooth...but NOT SO! i tested out w 1.15Ghz and found out that certain videos r smooth and other r not...and still dont know why. i know its not because of bitrate difference or HD because i tested out w 2 of my videos. Both r HD n have the same bitrate and yet one play smooth while the other are not. i know if u can overclock above 1.15Ghz...it'll probably smooth for all videos but it gets too damm hot....so its not a good idea. Even playin under 1.15Ghz gets hot pretty quick.
