my old Apple TV has an entirely different model number
My Apple TV has a different model number than any shown by Apples look-up page, so I am confused which version it is. The model number is MC572LL/A. It streams just fine except that it has begun NOT streaming our PBS shows lately. Occasionally I can jigger stuff around to get PBS for a little while. We miss our PBS streaming and need to know if we should buy a new Apple TV to get PBS. (PBS streaming simple says "not available currently". )
Our model seems to have been issued sometime between 2007 and 2014 perhaps. It is black w aluminum remote. It streams Netflix just fine.
