But I can't see 2-pass?
Since AE is a compositing app, not a editing or compression tool, it cannot do temporal compression in the way other programs do. Using 2pass would require it to hold all data of the primary pass in memory or store it as a temp file, which simply is not possible based on how AE works. Your AME being slow is due to the whole thing being a Dynamic Link extension and using multiprocessing. You do not have enough RAM, so one gets in the way of the other. Render a Quicktime file from AE, then encode it in AME. This would be the best solution.
Also consider 2GB of RAM is not adequate to render/encode with multiprocessing in a quad core machine. This is made worse by the use of Dynamic Link, which takes even more memory. Be aware that the 32 bit of XP has a combined ceiling of 2.7 GB for all applications, so you take advantage of more than that you would need XP 64, or Vista 32/64

Thanks for answers. Can I ask than; what must be my Quictime codec settings? I choosed best, but looks blury.
"Best" is a Render Settings template. Not related to Quicktime options. Go into the Output Module section and choose Quicktime format, and "Animation" in the format options. This is a lossless codec,
Thanks, I'll try
