<P>Often the need to resize movie images' size emerges. Its reasons can be many,

examples are decreasing output file size, encoding SVCDs to DivX. Ripped DVDs

when you want it to fit to 1 CD, and have good quality at the same time.

SVCDs have 480x480 size, and their header contains the aspect ratio the

player should use (Ex.: 480x480 + 4:3 = 640x480). However when encoding to
