HyvesTV is a product within the Social Network Hyves. Where users could make lists of YouTube video’s and share these with their friends on Hyves. They can for example add this to a humor or favorites video list.
[The website Hyves stopped per 02-12-2013, so this extension no longer exists]
When you are on Hyves you can easily add a YouTube video by copying this from another Hyves user. Within YouTube.nl there is also a share function that shows a Hyves Share button.
