Description : Is there a video sharing service that supports embedded chapter markers?
Last Answer : I know it isn't exactly what you asked for but Youtube supports links with time codes. So if you wanted to, you could put a link to each chapter in the description text of the video. This would allow ... at, say, 2:48, then just change the link to http://www.youtube.com/watch?v=OY9eTihrKM0#t=2m48s
