How do I know I am downloading a dvd movie/program with the best quality? I downloaded 18 episodes of Family Guy and burnt them onto a DVD-RW with Roxio Toast 6 Titanium. On some programs: the sound is off, the picture distorts, I am not able to search w/ FF, etc. Which part of the process is malfunctioning and/or what should I look for, for the best quality of video download?
