Hi we brought a new tv a Samsung series 6 UA40KU6000S with built in Freeview plus. We have a sky decorder so added a splitter to get tv as well as sky. We also connected to the Internet with fiber

My problem when using Freeview and on demand 1,2,3 it plays all for a few minutes then goes back to live tv.

Does any one know what's going wrong and how to fix it

Thanks
Jo-Anne
