DVDragon, Here is an example AVISYNTH script (for NTSC) the would convert a 16:9 anamorphic source into a 4:3 : LoadPlugin("C:\PROGRAM FILES\DVD-RIP\AVISYNTH\MPEG2DEC.DLL") mpeg2source("d:\location\infile.d2v") BicubicResize(720,360) addborders(0,60,0,60) ResampleAudio(44100) The math: 16:9 = 1.77778:1 4:3 = 1.33333:1 Conversion = (1.33333 / 1.77778) = .75 480 * .75 = 360 You then add the black borders to the top and bottom to make the picture DVD compliant (480 in the vertical direction). This script is often used to convert a 16:9 anamorphic DVD to 4:3 for SVCD use. Please note that you need to consider the TRUE aspect ratio of the source. Some "widescreen" pictures are not anamorphic. They are just 4:3 pictures with the borders already added. The "ResampleAudio()" command is just there to fix a bug when working with some versions of CCE, AVISynth, and Athlon processors... jdobbs
