[SOLVED] Video "skips" with fglrx

I have an ATI x1400 Mobility using fglrx 8-8.  During video playback, one every minute or two the video "skips," almost the way a CD might.  The picture freezes and the sound repeats itself.  Sometimes this only lasts for a split second, sometimes its extended for 5 or 10 seconds or more.  Once or twice it's not annoying, but it happens repeatedly, on any video file, in any video player (I've tried mplayer, vlc, totem...), and it makes it difficult to watch movies at all.

I borrowed my xorg.conf from my previous distribution (sidux), and then modified it slightly for Arch.  When the video problem started, I changed some settings around, but none of it has had any effect.  Here's what I have right now:

# /etc/X11/xorg.conf (Xorg X Window System server configuration file)
#
# This file was generated by fll_xorgconfig, the F.U.L.L.S.T.O.R.Y.
# Xorg Configuration tool.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)

Is this a known/fixable bug?

Re: [SOLVED] Video "skips" with fglrx

Add nopat to your kernel options in your grub config.

For more information look at this http://www.phoronix.com/forums/showthre … 183&page=6. There was also some discussion on these (arch) forums, but I do not find it right now.

PS: The catalyst drivers are really a pain.
