I have noticed that when I rip a DVD (to MP4) with the latest version of DVDFab, the MP4 exhibits poor video quality every second or so. It's blurry for only a split second. I compared it to movies I ripped a year or two ago (same DVD disk) and the quality is not the same. I ripped a movie that I ripped two years ago and the quality with the latest version of DVDFab is much worse. Am I doing something wrong? Has some option changed that I need to use differently? I use: MPEG4, I up the resolution, 2-pass, High-Quality, Frame Rate same as source, no split.
