Super interesting, it really depends on what you mean by "choppy".

Are you seeing the video re-buffer (a loading spinner re-appearing), or just the video looking stuttery?

My video engineer gut tells me that this is a frame rate conversion issue - do you know what frame rate your graphics card is outputting to your display, and do you happen to know the frame rate of the content that you're seeing issues with (or more generically, what type of content is it - film? TV) ?
