What do you mean by "skip"? If you mean the occasional frame is dropping, try changing the aspect ratio (press the "a" key) or zooming in or out a little "+" or "-". I have a PC with in ATI card in it which simply doesn't like playing back dvd's @ 1.33. It causes all sorts of video stuttering / skipping though the audio is fine. To this day I'm still not sure whether it's an MC bug or a problem with the video drivers. In any case, changing the aspect ratio which is often different in the menus to the actual feature) sorts it out.
