Share multiple videos on one page onto facebook page wall - facebook-graph-api

Question

I'm using Facebook C# SDK to post on fan page wall. (I created FBApp ext...) and using FB connect (Javascript) to user login, with this scope - "publish_actions,manage_pages,publish_stream". after user login i got an access_token to post on the page.
I have a page, and on the page settings "Everyone can add photos and videos to Testpage's timeline" is checked.
I can post message and picture, but when i tried to post a video (Youtube URL), it's appears on section "Recent Posts by Others on Testpage". When the Everyone can add photos and videos to Testpage's timeline" is not checked, I don't see any post.
To post a video on page, I must enabled "Everyone can add photos and videos to Testpage's timeline"?
When i success to post a video, Why the video appears on "Recent Posts by Others on Testpage"?
My Facebook user is admin on the page and I'm login with this user.
Thank's

To do this, you need to get the access token from the user accounts, and not from the FB.Login.
string getPagesTokensUrl = string.Format(#"https://graph.facebook.com/me/accounts?access_token={0}",accessToken);
using (WebClient wc = new WebClient())
{
var pagesTokens = wc.DownloadString(getPagesTokensUrl);
JObject o = JObject.Parse(pagesTokens);
for (int i = 0; i < o["data"].Count(); i++)
{
if (o["data"][i]["id"].ToString() == ConfigurationManager.AppSettings["YOUR PAGE ID"])
{
return o["data"][i]["access_token"].ToString();
}
}
}
