You need:
AnyDVD
ImagoMPEG-Muxer - A great quick, easy multiplexer
DVD Decrypter
(Assuming the DVD is not a retail dvd..)
1) Inset DVD and load up DVD Decrypter
2) In DVD Decrypter, click on the "Mode" tab and select IFO mode. Then go under the "Tools" tab and select "Settings". In the new windows click the "IFO Mode" tab. Under options set file splitting as "None". Click Ok.
3) Find the main film on the right. It's normally the longest one and found in the first VTS.
4) Click on "Stream Processes" and then "Enable Stream processes". Deselect all the boxes. Select the first box which is the video, and click "Demux". Then click on the Audio in English with the most amount of channels and click "Demux".
5) Now decrypt the DVD and when it's finished you should have a video file in the MPG form and audio which is either PCM or AC3. All we need to do now is remultiplex them.
6) Open up ImagoMPEG-Muxer and select your video and audio and select your output format as MPG. Click Multiplex.
This method keeps the DVDs original picture quality and sound quality, no loss at all
