It's easier to correct the aspect ratio before cropping, because DVD captures will be either 4:3 (non-anamorphic) or 16:9 (anamorphic). Some standard sizes I use:
720 x 540 - 4:3, non-anamorphic NTSC
853 x 480 - 16:9, anamorphic NTSC
768 x 576 - 4:3, non-anamorphic PAL
1024 x 576 - 16:9, anamorphic PAL
Going by eye, I would say the Hard Bastard images need to be about 25% wider to get the correct aspect ratio. This can be done using "Resize" in XNview...
...choosing "%" rather than "pixels" and making sure "Keep Ratio" is OFF:
