What's happening is your PAL DVD is being deinterlaced as video to 50 fps ('frame = 20 ms') and your rendering times are higher than the resulting frame time so you get dropped frames.
If this is indeed a video source then you need to lower your scaling settings.
If this is a film, enable IVTC or manually disable deinterlacing by pressing the shortcut (that's what I do), then it will play at 25 fps/40 ms per frame.
