JMF online demo movies won't play (Java Media)

[Will]

Question 1:

At... http://java.sun.com/products/java-media/jmf/2.1.1/samples/index.html

are some demos using JMF... they won't play on my XP-Pro.

I have the latest JDK, JRE and JMF installed.

There are 6 demo links and none of them will play.

The JRE and JDK are all working... and I can bring up JMF Customizer,
JMF Registry and JMStudio... so I think the JMF is installed
correctly.

Does anyone know what I must do to get JMF working or to see the
online Demo movies?

Question 2:

And, is the JMStudio a media player... like Windows Media Player or
Quicktime or what? It would not show me a .mov file.

I'm running XP Pro.

I new to Java and would really appriceate any assistance.

thanks - Will
