OT Why is it when y ou watch Youtube, you can press the left arrow to go back a little bit, and you can click on the progress bar to go back farther, but during a commericial, you can't go back. I would think they would be happy if you wanted to watch part of the commercial a second time. It means you're interested in it, instead of just waiting until it's over. Yet they went to the trouble to disable that.
What's with them. Is there any reasonable reason why they won't let you watch it again?
