When I use Nero, I get this problem, toward the end (anywhere from the beginning of the last fourth of the movie to the end) I get choppy video playback, almost without fail. The rest of the movie is fine. When I use other burners liek Easy CD, I don't get the problem. But I don't like using Easy CD since it gives more problems. Does anyone know of a way that I might resolve this? I'm burning only at 4 x speed.
