Issues Playing a Merged DataSource

Question

Hi, I'm trying to merge 2 audio DataSources, but when I create a Player for the MergedDataSource, I get the following error:
javax.media.NoPlayerException: Cannot find a Player for: com.ibm.media.protocol.MergingPullDataSource@4c624c62
     at javax.media.Manager.createPlayerForSource(Manager.java:1512)
     at javax.media.Manager.createPlayer(Manager.java:500)
     at Sample1.<init>(Sample1.java:25)
     at Sample1.main(Sample1.java:39)
This is my code:
public Sample1() {
          MediaLocator ml1 = new MediaLocator("file:/c:/dev/samples/sample1.wav");
          MediaLocator ml2 = new MediaLocator("file:/c:/dev/samples/sample2.wav");
          try {
               DataSource ds[] = new DataSource[2];
               ds[0] = Manager.createDataSource(ml1);
               ds[1] = Manager.createDataSource(ml2);
               DataSource ds3 = Manager.createMergingDataSource(ds);
               Player player = Manager.createPlayer(ds3);
               player.start();
          } catch (NoPlayerException e) {
               e.printStackTrace();
          } catch (IOException e) {
               e.printStackTrace();
          } catch (NoDataSourceException e) {
               e.printStackTrace();
          } catch (IncompatibleSourceException e) {
               e.printStackTrace();
Any help would be great, thanks.

Someone on the forum recently posted sucess doing that using the merge example, and claimed the Merge example produced a single output track under the condition that the input tracks were of identical formats.
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/Merge.html]
It's my understanding of the code that given 2 audio inputs you'll get an output with 2 audio tracks combined into a single file, but, the user (don't recall who) said they got a single track output... so the moral of the story is, I'm probably wrong and your milage may vary.
But I'd give the example code a few tinkering hours and see what it'll give ya.
