> it then produces a delay if the ad can't be downloaded, rather than silently skipping it. I've seen at least two other popular video sites over the years that had this symptom. (Can't remember them, maybe Hulu 6+ years ago?) One of them would occasionally have a weird overlap of the end of a commercial and the video. My guess was that the video was was queued to start playing after the length of the ad by some ad-independent logic.
