There is a bug in the youtube module which prevents some videos from working.
Here is an example video:
http://www.youtube.com/watch?v=_lxakVAaAJY
Youtube displays the following embed code:
HTML Code:
<embed src="http://www.youtube.com/v/_lxakVAaAJY&hl=en&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed>
However video directory remixed displays the following embed code:
HTML Code:
<embed src="http://www.youtube.com/v/_lxakVAaAJY&autoplay=1&fs=1&rel=0&ap=%2526fmt=18" type="application/x-shockwave-flash" allowfullscreen="true" width="480" height="385" wmode="transparent"></embed>
If I visit the actual url from the video directory's embed code, then as expected, the video does not play. This url is
http://www.youtube.com/v/_lxakVAaAJY...ap=%2526fmt=18
However, if you look at the end of the url, you will see &ap=%2526fmt=18
Now I don't know what this is supposed to be... but if I change that part to &fmt=18
then everything works fine.
