i've been using dvdflick to author dvds and then nero express to burn them. i recently tried authoring a movie with subtitles. i added the subtitles in dvdflick just as the guide said but i tried watching the converted files and there were no subtitles. i burned the files anyway and still no subtitles on the dvd. what freeware dvd authoring/burning programs burn subtitles? the subs are .srt files by the way.
