First, as Moth said, get rid of FieldDeinterlace

Second, since your picture isnt coming out right, ala looking squished or OFF

You need to adjust the values in the upper left and upper middle portion of the cropping/resize section of GK, these are for you to input the source material standard and select the DAR i believe

Also, in another tab of GK, if the DVD is anamorphic, I believe you have to UNTICK the box that says to encode to 601 standards, i forget what part of GK this is called, but just look for the check box

Adjusting these parts should help with your rip
