Hi My Phillips Flattv is about five years old and is HD Ready. Lately I've bin trying to watch movies on a memoriestick because on the side of the screen there is an opening for a memoriestick. However it does not seem to work. I can see all the films that are on the stick but cannot select one. Could you please advice me what to do? I tried different sticks that seem to work on other tv's. Thanks in advance,
