For some reason I'm not sure when it started but whenever i try to watch videos in the .avi and .mp4 format i can hear the sounds but i can not see the video. i've tried reinstalling the players and using different players but the same result.
My computer is a laptop sony vaio vgn-270g
2 gb of ram
t7200 intel core 2 processor
nvidia geforce go 7600 gt video card
Thank You for all who responds
(i will be gone for a week but once i get back i will try everything i read in this thread)
