Thanks for that last post, I found that opening up the graph editor in the timeline and then holding down mouse button to create a box and select all the animation points then enabled me to extend the duration of the animation, funny it is only in the background animations that I had this problem!

I have dropped the resolution down to quarter and it still makes no difference! the animation still only renders for 5 seconds and then becomes still for the rest of the clip!
