basically i have a video with overlapping subtitles in .mkv format but this is not a problem since the overlapping subtitle is actually a note putted in there that do not interfere with the other subtitle. the problem is when i burn it to dvd. when i play it the notes putted in there are replacing the actual subtitle (within its time frame) with itself. is there anyway i could fix this without changing the format/style/font of the subtitle? if its not possible a guide would really be appreciated
