[Paraview] long animations are freezing halfway through

[Richardson CFD]

I have been having trouble creating longer animations (150 frames)
from larger data files (1million cells). The animation works fine
initially but then freezes up about half way through the avi file -
displaying just a constant unchanging image. Streamlines seems to work
fine, but velocity contours (attached) is the one causing problems. I
am having to create the animation in 2 parts, creating 2 seperate avi
file and then join them after.

Any suggestions or similar experience please let me know. Regards Giles.
