What does each setting: Precise bicubic, bilinear etc mean. What is best for what type of movie? Like for example low action movies or high action movies.

Hi mangus

Use the Precise Bicube if you make a DivX that is smaller in Size then the Original.
Use the bilinear if you make a bigger Size in resolution then the Original.

This Filters "blur" the Pixels...so that you dont get quaders in your Movie.

I think that's backwards. From the Avisynth reference (http://www.math.berkeley.edu/~benrg/avisynth-reference.html):

If you are magnifying your video, you will get much better-looking results with BicubicResize than with BilinearResize. However, if you are shrinking it, you are probably just as well off, or even better off, with BilinearResize. Although VirtualDub's bicubic filter does produce better-looking images than its bilinear filter, this is mainly because the bicubic filter sharpens the image, not because it samples it better. Sharp images are nice to look at--until you try to compress them, at which point they turn nasty on you very quickly.
