I have two divx .avi files that I would like to make into a DVD. It is very easy with the DIVX to DVD option. However I also have a .sub and .idx file for the subtitles for each of the two .avi files. How do I make sure the finished product shows the subtitles? If I add the .sub and idx files to the Video_TS folder with the .vob file that divx to dvd makes before burning with dvd copier should this work?
