[Paraview] Save animation using python script

[Michael Martinec]

Hi

I have created a *.pvd xml file which loads timestep and *.vtu file data 
into paraview.
 From paraview i can then save the animation to a *.avi file nicely. I 
could also create a python script which loads the *.pvd file and brings 
me to the state before saving it as an animation. But I do not know how 
to save the animation from the script. What do I have to apply to the 
python script?

Regards and thanx for helping!
