Page 1 of Blurry horizontal lines across fast moving scenes in my Region 1 Metallica dvd

When i play Metallica`s "Cunning Stunts" DVD i get some horizontal blurred lines when the scenes go quickly from one to another like in an action sequence when one scene zips to another where there are people running around, can anyone tell me what causes these lines.

I am playing this Region 1 DVD on a PAL system with a drive that has been made multi-region, Pioneer dvd-105.

Thanks for your help.
