When you burn a dvd movie, it always gets good quality if you dont compress it to much, and if you compress a movie you can only see the "bad" result by stop and zoom the movie and see the pixels.
Even if you compress a movie to 50 % the quality is better than svcd.
But how often do you use the zoom when watching a movie?
DVD shrink is one of the easiest software to use, with dvd decrypter and nero.
When other people say some dvd burning software is not good and so, it doesnt mean it gets very bad result, only its unstable and doesnt work fine.
