First, get the embed code from YouTube. The sample below is the embed code taken from the "Information R/evolution" video. In the sample, you'll notice that I've made the URL bold and in red. Notice that the URL occurs twice. You can copy EITHER URL!!
<object width="425" height="344">
<param name="movie" value="http://www.youtube.com/v/-4CV05HyAbM&hl=en&fs=1&"> </param>
<param name="allowFullScreen" value="true"></param>
<param name="allowscriptaccess" value="always"></param>
<embed src="http://www.youtube.com/v/-4CV05HyAbM&hl=en&fs=1&" type="application/x-shockwave-flash"
allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
Next, replace the ADD URL HERE in the code below with the URL from the embed code.
<object width="400" height="326" id="VideoPlayback" data="ADD URL HERE;" type="application/x-shockwave-flash">
<param value="ADD URL HERE;" name="movie" />
<param value="sameDomain" name="allowScriptAcess" />
<param value="best" name="quality" />
<param value="#FFFFFF" name="bgcolor" />
<param value="noScale" name="scale" />
<param value="TL" name="salign" />
<param value="playerMode=embedded" name="FlashVars" /> </object>
Your result should look something like this...
<object width="400" height="326" id="VideoPlayback" data="http://www.youtube.com/v/-4CV05HyAbM&hl=en&fs=1;" type="application/x-shockwave-flash">
<param value="http://www.youtube.com/v/-4CV05HyAbM&hl=en&fs=1;" name="movie" />
<param value="sameDomain" name="allowScriptAcess" />
<param value="best" name="quality" />
<param value="#FFFFFF" name="bgcolor" />
<param value="noScale" name="scale" />
<param value="TL" name="salign" />
<param value="playerMode=embedded" name="FlashVars" /> </object>
Then, copy and paste the resultant code into an ANGEL page (or forum or dropbox or folder) and it should work. Try it with the above code if you'd like. It's a pretty neat video.
