here's the thing about them MAC address'
Take a look at both of them, even copy and paste them one on top of the other onto a notepad. Now you will notice that the last 6 digits are the same for each MAC I, while the first 6 are different.
example:
17:3c:2d:22:1e:6f
00:1a:79:22:1e:6f
The top MAC as seen above, is the device's MAC , it's the BuzzTV device's MAC. These MACs come with every device that connects to the internet, even a 'smart' fridge or that 'smart' bed, has a MAC ID
The bottom MAC which starts with 00:1a:79, belongs with the Buzz5 application, which is the BuzzTV's onboard iptv app.
The first 6 digits carry information to the server of what type of device this is and or location. This tells the server if it's a 'smart' bed trying to connect to their services or is it an iptv app.
It's more complicated then that but that's the short version.
The server connects to your BuzzTV's iptv app (the Buzz5 app).
It does not connect to the BuzzTV device itself.
It connects to the Buzz5's MAC-ID which starts with 00:1a:79 (or other depending on apps and devices being used, (but so far Buzz5 app uses the 00:1a:79 MAC-ID only).
So again, The 00:1a:79 MAC belongs to the onboard iptv app(Buzz5 app).
The Buzz5 app connects to the server.
The BuzzTV device itself, does not connect to the server, it connects to the world web web but not the iptv server.
You need the MAC that belongs to the app that connects to the server
As long as you are using BuzzTV's Buzz5 app and not the STB EMU app on that BuzzTV device.
