I recently had to update username and pw for directv stream credentials. I have rescanned TVE and get all channels except Fox Sports owned and all Discovery owned. I think ATT may have changed the way you login as i can watch just fine by going to stream.directv.com which of course redirects to ATT.
Any Ideas? Logs submitted
