First try refreshing your browser or try another browser. If that doesn't work, read the following.

All the videos on my website are embedded from Youtube. From what little information I can find Youtube is testing turning off videos for certain users that are not logged into a Youtube account or using a VPN to view videos. If you have a Youtube account, please try logging in and see if you can then view the videos on https://mvotd.com. If you're using a VPN, try turning it off to view the videos. There are a few other work arounds but they are pretty confusing to use. If you have the skills you might try searching Google for "Youtube Sign in to confirm you're not a bot" for a fix. I didn't see any that looked easy. Our best hope is that Youtube completes their test and realizes this is a big mistake. Until then, please check in daily to see if you still getting the error message. Sorry it took so long to figure out what was going on with this. Mel
