The Eurogamer report is fairly accurate. The deleting of feedback they are referencing is NOT from the Xbox.com forums. It is the private bug/feedback page available to beta testers via connect.microsoft.com.
http://forums.xbox.com/xbox_forums/xbox_support/f/30/t/157004.aspx is not even a relevant thread. That thread is explicitly about video buffering issues for streaming content and has nothing to do with the Eurogamer article.
