[Paraview] Exporting Animations from ParaView

[Alessandro Bellina]

Utkarsh,
I tried recompiling ParaView 3.3 from CVS and I am still having the
same issue with VTU/PVD files. It actually opens fine the files that
come from the Examples folder from ParaView but these VTU/PVD files
that used to work in ParaView 3.2.1 don't work anymore. Different
format?
