Looking for a little help if there are any Kodi experts in here.

Got an IPTV setup using an APP watching via the XBOX ONE.
Just had an update and now I get constant ads... fuck that. I would pay to get rid of the adds but it really is a proper shit app anyway.

So I remembered that KODI is now on the ONE so launched it and installed the PVR IPTV Simple client.
Installed and added my m3u and it loaded all my channels but when I click to play any of the channels nothing happens.
I saw lots of posts where you need to enable 2 settings to do with streaming and RTM or something like that. Enabled em both and still the same.

Anything I should try? Its a shame because the layout is really nice compared to the CRapp I was using.

Thanks guys n gals.
