FYI, my son-in-law is an "Evangelist" for Microsoft specializing in the entertainment industry and refuses to admit there is a problem with Media Room (I know that is the basis for U-Verse).  When I discovered the problem discussed in this thread, I asked him about it.  Got a typical Microsoft head-in-the-sand response.  I think it is very strange that AT&T will not disclose the truth about this issue, if not to its customers, at least to its tech support organization.
