VLC playback choppy when full screen

[GSZX1337]

I recently installed Mythbuntu on a PC with an AMD 780G chipset. I installed libdvdcss from the medibuntu repository (https://help.ubuntu.com/community/Medibuntu#Adding%20the%20Repositories). When I run VLC media player, DVDs play fine in windowed mode (at default resolution) but run choppy in full screen mode. I have installed the AMD proprietary drivers. I do not have Compiz running (can you have Compiz in Mythbuntu's Desktop Environment?). Any help is appreciated.

Thank you in advance,

I seem to have the same problem. See problem (The human eye only captures one on or 2 of that nasty chopp-chopp lines, not as many as the scr-print tool makes visible) Though it's not full screen, just stretched to ~ 200%
I get this with 8.6 and 8.7 drivers (can't remember and further..)

I tried playing some DVDs fullscreened in Totem. They played fine, so I know it's a problem with VLC.

Did you allready try all the video options intthe preferences dialog?
And plx post your xorg.conf, you may need some options to get full accelerated videos.

When I type:sudo gedit xorg.conf
I get a blank page.

When I type:sudo gedit xorg.conf
I get a blank page.

sudo gedit /etc/X11/xorg.conf shouldn't reveal a blank one..

I finally got back to my media center PC. Here's my xorg.conf

I'm sorry I haven't replied sooner, but the motherboard on my HTPC died so choppy playback is pretty low on my list right now. :P
