Cropping will change the SAR, at least thats what I was told in the similar thread I posted. This comment might be of use, I saved it and use this calculation...

"The actual way meGUI calculates the SAR is as follows:
1) Apply the cropping and then determine the aspect ratio of the input video image (inputPixelCountRatio).
2) Scale the vertical resolution according to the horizontal resolution that's been specified (resizedVerticalResolution = horizontalResolution / inputPixelCountRatio)
3) Adjust the vertical resolution so that it matches the closest multiple of 16.
4) Set SARX to the horizontal resolution.
5) Set SARY to Round(HorizontalResolution^2 / (VerticalResolution * DAR)), this is then truncated to an integer."

So if you're not resizing you can ignore 1-3 and use the horizontal and vertical resolution after you've cropped.
