I'm really struggling to understand the overall thing. I get what IPTV is and that I could watch a stream of a public IPTV channel on my laptop. But I don't understand the wider process of paying a sub, setting up channels and watching them on various devices. Is there a guide? Some questions I have, that would be useful to see in one place are:

• What's an m3u?
• I know what an EPG is but is there special config to make it work?
• Do all IPTV providers service work on new Samsung tvs?
• Do they need to be reconfigured occasionally? If so, how?
• Are the services all about as reliable as each other?
• Are the EPL games always on the same channel or do they require a bit of config each time? etc.

Thanks.
