While I can't answer for why this person didn't receive a reply, I can say that embedding video from other sites is probably not going to be a good idea. The reason is because most sites such as Dailymotion, Youtube, Metacafe, etc., have rules against embedding their videos on "for profit" sites. Most people who use vShare are looking to make money from their site via advertising. By doing this, you are violating the rules of embedding those sites content. Even if vShare could embed those links, if your site is discovered by the site you are embedding from, chances are that they will block your site from embedding their videos.
