Geoff,
>>EMBED CODE DOES NOT WORK ON NEWS FEED~WALL OR EMAIL USING THE EMBED METHOD
I have tried the code you used and, indeed, it resulted in "blank" box.
I have used another youtube code ( see bellow). And it worked.
Have tested with several random youtube codes and all went well. Could there be something wrong with your embedd code?
<object width="560" height="315"><param name="movie" value="http://www.youtube.com/...US&version=3"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/...US&version=3" type="application/x-shockwave-flash" width="560" height="315" allowscriptaccess="always" allowfullscreen="true"></embed></object>
>>>WHICH BOTH WORK BUT YOU HAVE TO TELL THE MEMBER AFTER THEY POST THE
EMBED CODE ON THE NEWS FEED OR THE WALL TO ERASE THE CODE IN THE TEXT
BOX AND LEAVE BLANK OR TYPE SOME THING THEN POST THE COMMENT ~THIS SEEMS
LIKE UNNECESSARY EXTRA STEPS AND THE SCRIPT NEEDS TO BE RE WRITTEN TO
NOT SHOW THE EMBED OR HTML ALONG WITH THE IMAGE, I HAVE WRITTEN MY OWN
SCRIPT FOR PHPFOX BASED SCRIPT FOR OUR OTHER SITES AND THIS IS POSSIBLE
You can suggest this toUserVoice .
