I find Twinview quite useful and I prefer not to abandon it...

I finally found a good solution : a script starts a second X server on the 
display :1 , and with a ServerLayout in my XF86Config which does not uses 
twinview. So that when I double-click on my favorite movie it turns on the 
second monitor but gives full acceleration on the first one. When I quit the 
movie it automatically returns to my dual-headed desktop
