I have this code and this error in FireBug:
Error: Permission denied to access property \'toString\'
How can i fix this error?>
Don't ignore this error just because its not related directly to your code.
It seems to occur when your embed is initialy hidden.
Just add ?html5=1 to your embed url. IE8 will still take flash version. or load your video with the Youtube api.
?html5=1
