Network server fails playing after 8 mins. every time. I have a Humax in 1 room on a win7 network & a 2nd Humax plus a Samsung tv in another room on the same network. After 8mins the server stops working whilst playing a video on the tv via the 2nd Humax from a video on the 1st Humax. It is necessary to restart the 2nd Humax to get the server to appear on the tv, it will then play for another 8 mins. and then stops. Any ideas anybody.
