YouTube decided to add a “related video” feature to embedded vids so that if you mouseover an embedded YouTube video that is playing related videos will popup at the bottom of the screen obscuring most of the video. Here’s an example of what all of YouTube’s embedded vids look like: (Taken from yesterday’s Two O’Clock Trailers)
There’s a way to turn off the related vids feature by modifying the video URL by attaching a “rel=0” (without the quotes) parameter to each video but there’s no easy way to do this for every embedded video in your archive. And I’m not the only one who thinks this feature is horrible.
Kudos to YouTube for listening to the complaints and fixing this immediately. You can still see related movies if you desire but by going to the menu instead.
