Multiple video's with SurfaceMapper

i am very new to Processing so i'm probably taking on more than i can handle.
starting out with the provided examples in the library i tried to understand what everything does and i've been messing around for some time.

then with an new sketch and only using GSMovie i managed to play 2 video clips next to each other. so i tried to do that in the SurfaceMapper example. i succeeded in adding a movie, i could get both to play (but they were both in the same QuadSurface. so i decided to set up 2 surfaces and link the different clips to the different surfaces.

there are 2 surfaces now but only the second one renders. the first one appears black in render mode. in calibration mode everything works but the whole image flickers.

here's the code i have so far:

import codeanticode.gsvideo.*;

import ixagon.SurfaceMapper.*;

import processing.opengl.*;

import codeanticode.glgraphics.*;

/***********************************************************

* EXAMPLE PROVIDED WITH SURFACEMAPPER LIBRARY DEVELOPED BY *

* IXAGON AB. *

* This example shows you how to setup the library and *

* and display a movie to multiple surfaces. *

* Check the keyPressed method to see how to access *

* different settings *

***********************************************************/

GLTexture tex, tex2;

GLTexture img;

GLGraphicsOffScreen glos;

SurfaceMapper sm;

GSMovie movie, movie2;

void setup(){

size(1600,1050, GLConstants.GLGRAPHICS);

glos = new GLGraphicsOffScreen(this, width, height, false);

tex = new GLTexture(this);

tex2 = new GLTexture(this);

//Create new instance of SurfaceMapper

sm = new SurfaceMapper(this, width, height);

//Creates one surface with subdivision 3, at center of screen

sm.createQuadSurface(3,width/2,height/2);

//set the name of the surface

sm.getSurfaces().get(0).setSurfaceName("name1");

//Creates one surface with subdivision 5

sm.createQuadSurface(5,width/3,height/3);

//set the name of the surface

sm.getSurfaces().get(0).setSurfaceName("name2");

movie = new GSMovie(this, "streets.mp4");

movie2 = new GSMovie(this, "montypythonlg.mov");

movie.setPixelDest(tex);

movie2.setPixelDest(tex2);

movie.loop();

movie2.loop();

}

SurfaceMapper and X11

hi,
i have been looking into the basics of Processing because i wanted to try SurfaceMapper.
I will have to practice but very basic code (tutorials) is working well so far.

SurfaceMapper however is a bit more advanced :p

mapping an image works already, still need to figure out how to map 2 different ones instead of the same image in multiple frames.

But when i tried the movie mapping example provided with the SurfaceMapper library i get an error message;

it says i have to install X11 to open Java. but i have XQuartz installed on my computer. the old X11 is still there too as it's impossible to delete. but if i try to open it i get a message to install XQuartz instead. and thats what i'm already using...

i'm confused now.
