This guide assumes you already have decrypted your DVD to the hard disk and probably already have created your WMV file. If you have not already done so, please visit the homepage.
The guide will show you more than one method of how to add subtitles to your WMV movie. To view subtitles in Windows Media Player you need to create SAMI (*.smi) files. To view subtitles in other players such as jetAudio, you might try creating SUB (*.sub) files.
This method is quick and easy. The only disadvantage is you cannot use these subtitles to play in Windows Media Player. You will need a third party directshow compatible player such as jetAudio. If you wish to view subtitles in Windows Media Player you can still use Subresync in VobSub to convert to SRT which can later be converted to SAMI files.
Start > All Programs > DVD to WMV Tools > DVD to WMV Tools
Right click the Form and click VobSub Filer or Press Ctrl + T. This will load VobSub Filter by Gabest.

Press open and browse for the IFO file of your movie.

Browse for the folder to create the subtitles. This may be the folder where your WMV file is.

All you have to do now is, selecting 00 - English. Press OK after that.

VobSub will now start creating the Index (*.idx) file and the Subtitle (*.sub) file.

You need both files in order to get subtitles to work. After the files are created you are safe to close VobSub.
The index file, subtitle file and the movie should have the same filename. For instance:
Kung.Fu.1986.The.Movie.wmv, Kung.Fu.1986.The.Movie.idx and Kung.Fu.1986.The.Movie.sub
You can now use jetAudio to watch your WMV movie with subtitles.
To use Windows Media Player you have to convert these files to .sami files. You can follow the Video Help guide here.
SubRip 1.17.1 or higher - If you are running Windows XP, you might need to change the compatibility mode of the program to Windows 2000 or Windows 98.
Subtitle Workshop or Subtitle Convertor
Open SubRip
File > Open > VOB(s)

Open IFO
Note: If your movie is based on the following VOB files VTS_02_x.VOB then the necessary file will be VTS_02_0.BUP.

It will show the related VOB files in the next window

Press Start

How you need to type each letter highlighted by SubRip. Each time you
type in a character SubRip rembembers the it.
So usually you will need to type that character once. But if SubRip fails to OCR
the same letter next time, it will prompt you to type it.
Do this procedure until it goes 100%.

In Subtitles Text Window: File > Save as > *.srt file

Close SubRip
You can open Subtitle Workshop > File > Open Subtitles
Browse for the SRT file. Then File > Save As and choose SAMI Captioning

Save the SAMI file with the same name of the movie file. For example, if the movie was National Security.wmv, then name of the SAMI file would be National Security.smi.

Place the SAMI file in the same folder where the movie is
Open Windows Media Player
Play > Captions and Subtitles > On if available
