Description of problem:
I'm using a multihead configuration (Laptop 1024x768 + Monitor 1280x1024) set up
with the next command:
xrandr --output LVDS --mode 1024x768 --pos 1280x0 --output VGA  --mode 1280x1024
--pos 0x0

When i open an video file i get a black window with a colored diagonal line and
flashing colored vertical stripes (see attachment) and the normal sound. When i
haven't attached my monitor, i can play video files without any problem.

Version-Release number of selected component (if applicable):
This is xine (X11 gui) - a free video player v0.99.5.
(c) 2000-2007 The xine Team.
Built with xine library 1.1.7 (1.1.7)
Found xine library version: 1.1.12 (1.1.12).

How reproducible:


Steps to Reproduce:
1. Connect a external monitor to the laptop and use xrandr to get to multihead
(note: due to a bug in kde you'll have to kill plasma and probably kwin too to
get a functional desktop spread over the 2 screens)
2. open a video file you know that has been working in singlehead mode.
  
Actual results:
As noted above, you'll see a black window with a colored diagonal and flashing
colored vertical stripes. Sound does play normal. Note as well that your CPU
increases dramatically... Xine starts responding slow after a while, so don't
wait to long... 


Additional info:
I did attach a screen shot and a bug-report created in verbose mode (using xine
--bug-report command)
