Dvd+rw on dvd movies playback?

is it good to watch dvd movies on a dvd+rw or i should just get a plain dvd rom? because everytime i play a dvd movie on my dvdrw my cpu usage jumps to 100% and the picture is so choppy. i tried putting the hardware acceleration bar all the way to the left and it’s still no good. i tried 2 video cards and still the same.
