GuiTheoraCtrl controls? Where?

Does anyone know how to have access to GuiTheoraCtrl controls?
For instance I want to change the size of the video window and it's position or change the layer. Make it layer 5 for instance. Or loop it.

I can see some:

%guiContent = new GuiTheoraCtrl(MyVideo) {  
          profile = "GuiDefaultProfile";  
          horizSizing = "relative";  
          vertSizing = "relative";  
          position = "0 0";  
          extent = "400 400";  
          minExtent = "8 2";  
          visible = "1";  
          done = "0";  
          stopOnSleep = "1";  
          backgroundColor = "0 0 0 255";  
       };

I can see some booleans. What is done = "0"; , stopOnSleep ="1"; ?

Why changing position and extent doesn't affect my video?

I've searched the whole site, there is no information whatsoever about it.

Please help if you know something about it.
