Im sorry for my crappy english but im going to do my best.
When a watch HD movie with the x264 format the movie laggs but i heard that it can be becaus a por graphic card or a por CPU. But a friend told me that if a change a setting in the VLC player i can watch a x264 movie.
i dont remember what i was so im wondering what is it that can help my computer so i can watch a x.264 movie.
If there this is importan i have
AMD A64 2x4200+
Geforce 7800GTX
