Xorg crash

[cliff tinker]

this happens every time i try to play video regardless of which video player i try to use. i have totem,vlc and miro installed and as soon as the video tries to play i am logged out. also whenever i log in the screen breaks up into stripes for nearly a minute as the desktop is loading. i hope someone can find a solution to this.
thank you
