I read some articles but I still have this question where I couldn't get a clear answer to.
So I want to buy a Mag Box 322 but I heard that Mag Box users have to provide their MAC Adress to use an IPTV Provider, the IPTV Provider always ask for the MAC Adress when you want to use it in Mag Box. But is that even needed? Is it possible to just enter the regular m3u link with username and password as you do on Apps like Smart IPTV instead of giving away the Mac Adress of the device? So is it possible to just enter the m3u link of an IPTV provider instead of giving away the Mac Adress to them?
I don't know how much you know, so I'll explain a bit. If it seems like I'm explaining too much, please be patient.
Here's the thing, your MAG box isn't simply a video player, it runs an application that will login to the server, request a list of services (channels/vod/weather/etc), and when you play a channel it requests the play link for it on the fly. The mac address is the username/password.
What you're asking for is akin to saying why doesn't Netflix just give me ftp access to their storage folders instead of giving me a username and password to their website or apps.
Why this setup?
Can I refuse?
Sure, you can tell your provider that you don't like this system because it gives them too much control, but in most cases the answer will be "ok, bye". This system saves them massive amounts of time and headaches in most cases. If they're desperate for your money, they may offer alternative arrangements.
I hope this answers your question.
