[Joseph Russell]

Thankyou Tim, Mike and Lance for your suggestions. I have taken them all on board and along with some suggestions from other forums I have come up with an acceptable work around. It is as follows:

I cleared out all unused clips and timelines from the bin to reduce the size of the project dramatically,

Deleted the Magic Bullet plugin and all reference to it.

Rendered slow motion effects and titles in After effects to take some of the load off premiere

And I installed Mem turbo RAM Mangament utility (I will also try the one you suggested Mike)

So far these this has enabled me to render out my project successfully and with any luck I will be crash free on the next episode.

Thanks again,
Joe
