My system is Gateway G6-350, 256 MB Ram, 5G HDD, ATI Rage Pro 8MB. my DVD player is Mpact - ECenter, every time when I play dvd movie I have to "ADVANCED GRAPHICS SETTINGS - Hardware acceleration " turn "FULL", but if I leave my system in "FULL" setting for regular use, it will freeze my whole system, then I have go back to turn off the setting again, any idea can fix this problem? Thanx !
