When decrypt the dvd I see 5 OR 6 huge vob file about 1GB but on dvd disk around 40 or 50 songs how do I rip the individule song like extrackting audio songs is it posible?.

Thanks

You could use DVD Decrypter and then choose IFO mode and rip what you need i.e just the audio track and then you can edit this to whatever you require.

Alternatively you could rip the VOBS you want and then demultiplex to video and audio streams and do what you want with the audio file.

Hope that helps ?
