Hi Stuart, sorry I can't answer your main question re the 'wizard update'.
As for IPTV Stalker it's the same for most people unless you want to jump
through a couple of hoops and urls etc. Problem is it is now a paid for service,
there are a couple of threads about it around the forum. If you wanted you could
update 'Kodi' yourself, and run 'Hushams' wizard. Once again there is a thread about
this on the forum. I did it a few weeks ago with a T-8 box and haven't had any problems
yet!!!
If you don't want to go down that path then depending on what you want to watch there
are a few pretty good add-ons around, "zeus""genesis""icefilms""vdubtv25""ukturks""1channel"
with those you will get most movies, tv, tv shows and sport.
Chris..
