there is a plugin called iptv under the plugin files. this links to a lot over the world. ( tested some ) there is a way to edit the file to get uk channels as well, but i havent tested that part
most use vix, but just dont think like a lot on here that the newest firmware is the best and there is still no need for you to do basic things.
channels move, so make sure add the cross epg and the ABM for when freg change.
