It sounds like you have written a great plugin. Exactly what I need for the site I am putting together. However the videos are not displaying on the page. I get a black box where they should be and nothing else.
I used your [youlist pid="PL3FF15AA7ED356D9F"] shortcode as a test and nothing is displaying.

I also noticed that the pid for my playlist was much longer:
I am guessing that is just YouTube updating their system
Would you have any insight into what might be creating this problem. I have done the normal steps of using the default theme and deactivating all other plugins.
Here is the link to the site. Thanks for any insight you can give.
It is on a temp server while under development. I can't imagine that would cause the problem.
