I am using winavi to convert a series of mkv files into dvd then burning them it works fine except for subtitles sometimes appearing late or in some parts not at all after converting the mkv to dvd. The majority of the subtitles still show up and in some episodes I have no problems at all but since its in japanese I need all the subtitles to be working right. Anyone know how to fix this? Also when playing dvd on dvd player for a standard tv the subs are sometimes a bit off screen.
