you find both m3u and mac based here look in the archives for m3u`s
one should understand the difference between a m3u and a mac based service
the m3u uses the username/password format the mac based uses the mac format

sounds like theres confusion between the mac on the buzz box app and the mac for the iptv service
also why would the box ask for the username/password if your using a mac service maybe the wrong setting
i dont own a buzz ?
the link you provided should have a mac number with it 00:1A:79:XX:XX:XX
