I have an Icybox caddy with a 160GB HD in it that I am trying to hook up through the USB but it isn't recognising anything on it. I want to use it for film and TV show playback. I have named a file "Video" but it just won't recognise any files. I've put an episode of "Born Survivor" in the video file on my 1GB memory stick duo from my phone and that works fine. What am I doing wrong?
