Toast Titanium 18 in Toast 18 Posted August 29 · Report reply It would be weird if this issue is only occurring on playback on a specific device. Any DVD player, including software DVD players, should play the same. Can you test on any other player as well? The high speed audio would then be a conversion error, possibly induced by uncommon audio characteristics of the source audio (e.g. not 48 kHz). Toast should convert it correctly, but odd audio in the source would be something to look for. What does it say for the audio specification after you add the file to Toast?
