With subtitles

hi could some one please help me i am trying to burn a dvd with greek subs using convertxtodvd but when i play it on my dvd player the subs dont mean anything they are just lots of letters eg aeuoihu@fhgth.
how can i correct this, if i watch it on the comp it all plays fine. thanks.

Two things, ConvertXtoDVD is corrupting the files or your DVD player doesn’t support greek subs. Most likely the player.
