Can't play embedded YouTube videos in Chrome. Won't load and shows a black box. Try resetting Chrome browser settings.

I've been having an issue with Chrome for a few weeks where it won't play YouTube videos that are embedded in another webpage. It just shows me an empty black box with no thumbnail of the video or playback controls.  If I go directly to YouTube.com to watch the video, I don't have any problem. Embedded videos play fine in Internet Explorer.

I tried manually disabling all of my Chrome extensions and clearing my cache but none of that helped.  Just today (8/20/2013) I see that there is a new Chrome update available. One of the features is a new "Reset browser settings" button.  It resets everything back to the default settings but keeps basic customization like bookmarks, themes, etc.  I thought it would remove all of my extensions but in fact it simply disabled them.

I'm glad to report that this DID fix my issue with embedded videos!  I then went back in and enabled all of my extensions again and the embedded videos are still working! Woo-hoo!  So whatever this reset did, it took care of my problem.

Here's how you do it:

1. In your Chrome menu, hit the icon with the 3 horizontal bars (called "Customize and control Google Chrome")
   
2. Select "Settings"
   
3. Scroll to the bottom and hit "Show Advanced Settings"
   
4. Scroll to the bottom again and hit the button labeled "Reset browser settings" as seen here...
