Hi again, I've made a small test and the rendering in Opera and Chrome is different. I don't know which one is correct. http://perso.telecom-paristech.fr/~concolat/html5_tests/webvtt-overlapping.html <http://perso.telecom-paristech.fr/%7Econcolat/html5_tests/webvtt-overlapping.html> In Chrome, when 2 cues are active at the same time, and the first one becomes inactive, the second one is shifted down by one line. The next active cue (the third one) will be displayed on the line above the second cue. In Opera, the remaining active cue is not shifted, it does not move. The next active cue (third cue) will take the empty space below the active cue. This leads to strange results. In the above test, this is visible at time 16. Opera displays cue 6, 4, 5 (from bottom line to top) while Chrome displays 4, 5, 6 (bottom to top). I tend to prefer Chrome's behavior as this gives the same result if you split the overlapping cues so that they do not overlap (see my post for more details http://concolato.wp.mines-telecom.fr/2012/09/12/webvtt-streaming/).
