Didn't dare to do this with the old PC - when just one instance would crash, sometime... but now I dare, oh yeah, and I like it!

FIVE - I say 5 VirtualDub instances at the same time (with related AviSynth scripts) - four for a single project, split in four parts, and one for another project, that can't be split easily; and, as the CPU is from 80 to 90%, I think I reach the top... so, I've found the right way to speed up the encoding process!!!
...and meanwhile, I'm surfing the web, and listening to a CD (old dinosaur, I know!)
