> The switch must have some horrible buffering policy where one port ( the tv port ) can hog all the buffers and deprive every other ports of being able to send...
Or could it be that the switch is oblivious to STP ethernet addresses and PAUSE frames ? The frames shown(presumably originating from the TV) have a destination address of 01:80:C2:00:00:00 , and if the dumb switch doesn't know that this is kind of a special address, it'll just do what multicast bit in that address tells i to do - copy the frame out to every port..
