Flash objects do not obey z-index. This is particularly often found on youtube vids..
To solve this, pass wmode parameter with transparent value... like this: www.youtube.com/embed/somecode?wmode=transparent

$(function() {}); seems to wait for document ready forever, if it's invoked on a popup. Well um.. or probably because the document is already 'ready', the piece of code inside that function won't be even executed.
Instead, put the thing inside that function near the end of </body> tag... please, only if it's a popup. lolplz..
