Thanks for your reply.
But I am pretty sure that via Software Update I have updated to v 2.0.1 and yet these filters were not included in the Software Update install.
Should I then simply download the updater from the Apple site in order to obtain the three plugins? Would there be any harm in downloading the updater which my machine is already running?
Is this common that updates via Software Update in OS X do not include certain incentives like plugins? Is this an issue with registration that Software Update cannot integrate?
Thanks,
