Apple TV (3rd Gen) - No Album Art Since Update 5.1

Hi, since the latest update this week, I no longer get any album cover art on my iTunes Match library. I can't even so a successful restore on the unit...it downloads it, installs it and then says unsuccessful and suggests a restart.

It all seems to work other than the lack of art...any suggestions? For info, I have done all the restore/reset options. I am on a wired network.

TIA

EDIT: I can't even connect to my Photo Stream on the ATV (fine on my ipad and iPhone) (Apple TV can't connect to the service at this time. Please try later.)....is this due to the ATV, or Apples useless network/service again?

Never mind. In case it helps anyone else, it is down to the latest update running on Ethernet. I switched to wireless and its all good. Well done Apple, you have yet again produced another completely crap update!!
