of course there is, there always has been.
But iptv66 did not do away with MAC method, they just added another method, which is actually a method that been around longer then the MAC method and many use both to satisfy the multiple devices being used. This was added to NFPS services almost 2 years ago now.
This is not anything new, m3u and playlists is how iptv really all started.
maybe if they wanna lose money ..
the best boxes for iptv are mac driven bro come on ...
i guess we can agree to disagree..
