I've got strange behavior when using the FB Graph API to read the feed of a group I am administrating. Everybody in this group is posting YouTube links and I wanted to write an App to crawl them all into a nice list.

But depending on the user who posted I get one of the following results:

a) type=video and everything is fine b) type=status and I have to parse the link from the message instead of having a link field c) type=status and the link is not even in the message d) some users' postings are not in the feed at all

Does anybody know how to really obtain all message? I can see those posts including the links perfectly well using the Facebook web site...

Already tried to give each and every access right to my app, didn't help either.

I think I found the "problem": The result depends on the privacy settings of the user. Don't know why I can see the posts in the group but cannot automatically crawl it, only thing that happens now: I can't use the Facebook API but have to use some kind of HTML-parsing-crawler. Don't know why FB forces me to do that.
