If you are encoding from DVD source to any profile other than PSP DVD you will need to CROP the video unless the video stream is actually 16:9. Use the CROPPED dimensions in the spreadsheet. Do not forget to pass the crop commands to your encoder -croptop X -cropbottom X -cropleft X -cropright X
Please realize you only need to enter Width and Height of source video you are trying to encode. Everything else is just calculations or setting up screen size. You can read the rest to learn, but do not modify it.
Use the generated Width, Height, Aspect, and Padding values in your encoder program.
The view width and view height are just to let you know what the results will be of those settings.
