Maybe someone here has any ideas what the cause could be? I Converts my movies with ConvertXtoDVD 4 and burn them with Nero 9 and everything works fine, but when I play my movies on my Sony DAV-SC5 the subtitles will disappear after a while. DVD’s works great with subtitles on the PS2 and another DVD player I have, but not on my Sony. Have tried different brands of discs . Any sugestions???
