Hey guys,
Forgive me if this has been posted but I did not see anything when I did my search. Maybe I just had bad search terms. Anyways, I've had this same problem on Snow Leopard, and now on Lion. I can load a video in full screen in any player (Quicktime, VLC, MPlayer) as well as browsers (Chrome, Firefox, Safari) and it will play fine with both monitors on. As soon as I turn off the second/unused monitor, the video becomes choppy. Does anyone have this problem? Am I missing something?

Dell Optiplex 755
Intel Quad-Core 2.4ghz
8 GB DDR2 SDRAM
nVidia GeForce 8400 GS 512MB
Dual Acer P215h Monitors 1920x1080/60Hz

I had the same issue.... http://www.insanelym...p;#entry1764882
didnt get any response on this board but a little tinkering and i found two things.
#1 Use nvenabler in S/L/E instead graphicsenabler
#2 get rid of applegraphicspowermanagement.kext in S/L/E

fix permissions and reboot
