Here's how you make a link work verses imbedding the video itself.
take a piece of text and highlight it in some way to make it distinctive
I make it bold and change the color.
GREAT SOUNDING MUSIC
Then, with the text still selected, use the insert link tool on the editing bar.
Its the 7th selection from the left on my editing bar.
When you click the link editing selection it will give you a popup : insert your copied URL to the video here.
I copied a video URL and pasted it in to the link popup.
This way all a potential listener wants to do is click the link. The rest of the thread viewers don't have to download the video in order to watch the thread. Everybody wins.
