how to put subtitles in DivX film

Hello.

I would like to know how do you put subtitles in a movie. So there will not be 2 files e.g. the movie.avi and the movie.sub. But the subtitles would be already integerated into the the movie.avi so there will be no need for an external file with subtitles. How do I do this?

I think you can use TMPGEnc or mabye Virtualdub.
I found Virtualdub a while back on Sourceforge, when i was looking for g3 Torrent.
