I have a KDL40EX713, BT broadband and a Draytek router.

iPlayer has worked fine in the past, but for a while now (a week or two) we just get a message saying that the server is temporarily unavailable, and to try again.  iPlayer works fine on the computer, but we never get past the server unavailable message on the TV.

I've done the factory reset, but it has not made any difference.

The firmware is up to date.  The internet content has been refreshed.  The network connection is fine, and other network services on the TV are all up and running without any problem.

Anyone else having this problem?  Any suggestions?
