Editing out the Undot() line in your AVS script doesn't do nothing, still says Only SEEMMX CPU's Currently supported. This kinda sucks, I encoded lots of movies using other programs (slowly like 8 hours, but surely done), why the heck is Gknot so picky on Cpu instruction?? MMX is good enough to encode video. Updating my Cpu, pretty much means updating the motherboard, thus getting a new computer which I'm going to pretty soon, but a rather have this comp encoding movies while I use my new comp for other more powerful things such as pc gaming, I'm a heavy gamer, see where I'm going with this? There must be another way around this, please anyone?
