In the first post I've added a modded plugins package. All the key plugins have been recompiled using SEt's threading fixes and an extra tweak that prevents the main crash that I see when multi-threading. I can't guarantee they will help, but they might be worth a try. They won't prevent running out of memory if you use complex settings/many threads.

Read the instructions in the zip before asking what to do with the contents.

Instructions for stability and getting the best out of SetMemoryMax & SetMTMode are also in the first post (and the QTGMC instructions).
Also covers the EdiThreads setting, which is best set to 1 if you're getting problems.
Some people's computers simply don't like SetMTMode. Nothing to be done except fix AviSynth.

I don't recommend MT("") unless absolutely necessary, because splitting up the image will affect motion analysis (you always get problems at the edges with MVTools, with MT("") you have edges in the middle of your image...)
