In the new skin I can't find out where video responses to a video are listed, nor which video a video is in response to. Is the information still available, or did Google forget about it in the redesign?
There should be a panel below the video containing all video responses, including a link to the video it's a response to.
To find out whether a video really has responses, go to:
Replace vidid with the video's id. If there aren't any video responses, you'll get an error message telling you this.
