there has been a copyright battle going between warner music group (WMG), and youtube.. which I found out the hard way. There is a way around that though as long as your videos aren't generating any $$$
I've added links to Youtube videos on my Wordpress web site pages with no problem. The trouble began shortly after I embeded video (firewood video) into a web page. After about a week the video disappeared from my Firewood web page. An "f" was in it's place..... ok, just got back from web site. Seems I had the SmartYoutube widget installed, but improperly set up. Hopefully this resolves the issue. http://treetom.net/bulk-firewood/
