I use AnyDVD to decrypt the DVD. Once decrypted I use CloneDVD (Newest Version) to shrink the DVD into DVD-5 using the first option “Copy DVD Titles”. I erase everything accept the main title, audio, and subtitles. I erase all audio/subtitles accept English. So basically I have the Main Title, English audio and English subtitles, and that’s it. I burn at 8x speed and use CloneDVD to burn the movie as well. My latest movie had the worst quality at 69%, that is “The Shining”. That was after erasing everything accept the Main Title and audio. I was planning on buying DVD-R (DL) for the movies with bad quality but I hate to spend the money if I can find a solution using DVD-R.
