YouTube have implemented a change to the embedding player which displays a nice little display of 'related' videos at the bottom of the video window, permitting the user to go on to see videos, from other youtube sources, playing in the window on our wordpress.com blogs. Sometimes this is good, sometimes it's not. YouTube have provided an additional parameter to turn the feature off, needing a modification to the code.
My question/request here is for help/guidance on how to code the parameter. Any takers, please?
