Note that the PALs also look horizontally squeezed compared to the NTSC versions, something we saw on the Ewoks tapes as well.
That's only because PAL DVD stores images at 1.25:1 (NTSC stores them at 1.5:1 so "raw" screenshots of NTSC fullscreen DVDs are stretched instead of squeezed).
I didn't crop off all of the black padding but this approximates how your DVD would look on a TV: http://check2pic.ru/compare/28601/
