Created clone doesn't work??

Question

Thank you for your attention.
I am doing a project on transmiting video and audio from a server to some clients. It works well on trasmission, but I would like to show the visual component on the server computer during transmission and I get trouble in here.
My original method is use medialocator "vfw://0" to form a DataSource. And then use this DataSource to form its clone. I use the original DataSource to create player for visual component. On the other hands, I use the clone to combine with audio DataSource to form a merged DataSource for transmission. However, as the result, the transmission is fail in this case.
If I use clone as player for visualcomponent and original datasource for transmission, the transmission works well but the visualcomponent is fail.
Can anyone give me some advices??
My code in creating clone is as follows:
          try{
               vcDS = Manager.createDataSource(locatorV);
               if (vcDS== null) {
               System.err.println("Cannot create DS for VisualComponent.");
               System.exit(0);
               ds = Manager.createCloneableDataSource(vcDS);     
               if (ds == null) {
               System.err.println("Cannot clone the given DataSource");
               System.exit(0);
          } catch(IOException ioe){
                    System.out.println("IO Exception!");
          } catch(NoDataSourceException ndse){
                    System.out.println("No DataSource Exception!");          
          createPlayer(((SourceCloneable)ds).createClone());     
//           createPlayer(vcDS);     
          MergedDS = createMergedDataSource(locatorA, ds);

hi
andrew i worked on similar application, according to my knowledge
once the datasource is converted to cloneable datasource u must no longer use the original datasource , better create two clones and use them.
