Issues with High Render Settings

[loughran_matthew]

I recently posted this message on finding a the best proven technique for rendering a scene with animated objects in it. To no avail. So i post again with my settings and issues with a plea for help??? I have been rendering accross a network and have tried rendering with an irr map and just on single frame and the flickering results are the same. The animated objects are a mix of animated scale transforms and animated path deforms. All elements have animated visability. I have have incrementally tried turning up the qmc and rqmc subdivisions but this has made very little difference to the problem, and has mostly just increased the render time, which is now at 23(ish) minutes per frame. I have added some screen grabs of my render settings and the problem areas. If you download the two frame png's and flick between them quickly the problems will soon be obvious.
Please help, i have a deadline for tuesday (06/03/07) and really need this problem fixed as it is making my brain hurt!!

Vlado, i understand you are the man to plea too??
