How to encode without IFO file ?
Well, this is not very difficult.
But, before doing it, you must have a length of the movie, and to know the right sound track.
First, go to option and active the option Disable IFO by click on Yes, Do It.
After, go to Normal Encoding not pro. Neodivx will not ask you anymore the IFO file. Fill all the stuff, and in the end, click on encode. Then, enter the movie length in second. Neodivx will then encode the movie, and extract all the sound track from the vobs.
When the encoding will be finishied, you will have a MOVIE_1.AVI and all the sound track ( ac3 or mpa). Transforme all the track to wav using for ac3 AC3 To Wav, and for MPA, MPA to WAV. After, listen all your sound track. Find the one you want. When you find it, normalise it, and merge it with Multiplexing command.
And your divx will be made!
