New to JMF my players just showing a white screen

Question

Hello
I'm an experienced java programmer but i am new to JMF i'm having trouble applying an effect to a video track i've registered the effect successfully however when i then apply it to the video track all i get is a white screen. the player displays the video fine without the effect plugin applied however when i apply the effect it all goes wrong. i've checked the plugin viewer and data does seem to be moving between the various plugins and when i use a print statement the data is coming out of the plug in correctly. below is my code the player follwed by the effect file. its a real mess because i've been playing around with it for hours trying to get it to work and it's driving me crazy please can someone help!
Thanks
