Question I can't see video links

I've been noticing that in several posts where video links are, they don't show up on my screen. I'm not sure if anyone else is having this problem, but I've noticed it this week. Nothing has been changed on my PC.

Have a look at the one below if it shows. If it doesn't then there must be a problem with the installation of Flash on your browser. To diagnose that visit adobe.com

Thanks! I can't see what you posted. I'll go check my Adobe now.
