Thank you so far Elvis,
But I need your help to really push PIL3 to the limits in terms of emiter size and length.
Looking at the taskmanager I find under physical memory the total memory, the available memory and the system cache.
Could you -for example- tell me which percentage of which memory count, the size of an emiter avi can be? (say 80% of the available memory or so)
If I know how to calculate things, I can push the limits without having to try many options.
