Try setting the video mode to Red October Standard, and the Audio to WASAPI Exclusive Mode. That has helped others recently.
I would advise turning on "Video Clock" in "Options/Video/General Video Settings" as well, as that can help with many issues.
Also there are many threads discussing video breakup, and a lot of different causes for it. Search the forum to find ideas about what your problem could be, if the above doesn't work.
