Good point, but upgrading to 1.7.0.0 should fix the lipsync delays reported in this thread, which was much less than what you would get from bluetooth headphones (~2ms versus ~500ms) - that would be impossible to watch (or fix). Bluetooth is not a solution for anything with video - only for audio (unless you are playing an instrument when it is useless also).I know that this is an old thread. Have any of you that are having sync problems been using bluetooth headphones? It will add a perceptible delay. Try a wired set.
