I'm redesigning some sites to be responsive, but have found I can't get your plugin to adjust its height correctly.
I've put an example up on http://gavinwebb.com/wp-sandbox/
Here is the shortcode I've put into a text widget:
[youlist vid="N_ZFETatNTY,-4TJBTddP3A,g2axLFDjTgo,qXOrJtn1h2M,0n4E2tAQBVE,ej5L3aJMlPA,A3YxvySQqkk,F5_N86Pblj0" style="width:100%;height:100%;"]
I would have thought that this would have worked, following on from a previous support post here.
