I just had this exact problem. First in a short VOD the video got ahead of the audio. No biggie but annoying. Later, 20 minutes into a 3 hour VOD, an ad played making the audio turn chipmunk, speeding away from the actual video. I'd estimate that the audio was going 1.5x faster than the video based on the rate of separation and that 1.5x is the fastest speed I can still understand people on YouTube (where altering playback speed is a feature)
