I have inserted a video from youtube into a DIV tag, used the actual "embed" code found on youtube site. and used jquery to show/hide the div.

when activated, the flash video shows perfectly in the div, when clicked it plays as usual the only problem i have is when someone using a Mac, and clicks on play, the flash video disappears. this happened on many Mac computers regardles of the browser being in use ( none Firefox neither Safari are working ) although i have tested it on all general browsers on windows and it works fine
