I had read on an earlier post of yours explaining this and thought, well thats easy enough, however after several attempts it showed as "invalid link". This morning it was working normal for some reason I cant explain. I decided to do the same on the original post in this thread. I chose "modify" them highlighted the link, then clicked the YouTube tab, and it appeared exactly as both you and G illustrated. When I clicked "save" it shows as an invalid link. I am useing a tiny notebook with a limited version of 7, and have other issues at times, and wonder if that could be it.At this writing the original post in this thread shows as "invalid link" on my screen, It may be showing fine on yours/others. Thanks for the reply, we'll gitter figurd out
