I've been using a cable sub for a couple of years now and like many others on here am getting frustrated with the amount of freezing on some of the basic channels. So I thought I may try an IPTV sub to run alongside for a while. I have a new 4K Sony smart TV (android based) and access my cable sub through an Xtrend 8500. Would I be better setting up an IPTV sub on the Xtrend or finding an app for the tv and feeding it into there directly? Opinions would be most welcome.
