The box does NOT include any IPTV subscription. This is where you enter the login information for the service you purchase.
You need to buy a subscription, and when you do, they typically offer MAC type connection, XC or M3U. My preference is XC, but that is personal preference.
Discussion about IPTV services is NOT permitted in this forum (you will need to find another forum). Only discussion about the BuzzTV 5 software or the Hardware (in the appropriate sections).
