I am using dvd shrink/nero 6 to burn to dvd-r, and almost all have problems, with freezing up, stuttering, pixellation at various times throughout the movie. I am using verbatim discs, so it can't be the quality there. What am I doing wrong? The progammes (dvd shrink/nero) have no error messages, and am trying to limit the compression in longer movies (usually can get to at least 79%. Some movies have the occasional glitch, however most are just not worth watching. What can I do?
