Hi, try this to begin with
1 in Samsung tv app store see if the app smart iptv is available. Search for it in lifestyle or enter smart or. Iptv and it should come up.
2 find your IP address for your box
3 on a PC go into the IP address of your box and then select autobuqets
4 click the TC screen next to your main list and you should end up downloading a playlist.m3u file
5 go to TC, open smart iptv app and it will tell you your to MAC address. Write it down or take a picture.
6 go to the website instructed on your TC screen now and when prompted enter your MAC address and then browse and upload the m3u file
7 enjoy!
i found that the narrator audio was streamed some channels instead of standard, so you got a description of what was happening, bbc1 HD had that and no way to alter it, standard bbc1 west minds (or wherever you are based) had standard audio.
That should get you a bit further. Post back if it's not working and will try to help.
