Streaming problem with Apple TVe
i have an ATV which I have been using to stream the contents of my iTunes library from my Late 2009 iMac to my HD TV. Of late, I think since tthe last update to the ATV software, the waiting wheel just keeps spinning for a very long time when I am trying to watch a movie. The movie does start playing after a very long time but then stops, apparently when it has used up the data it has buffered. It starts playing again after it has stored up some more data but after a long time and stops again after a while.
There seems to be no problem streaming music or displaying photos. It seems to be a slow wi-fi problem, but the network signal strength seems fine, four to five bars out of the maximum five.
Would be grateful for some pointers to a solution.
Thanks in advance
