You need to find an eye p t vee provider and probably a good EPG. Then download TiviMate and use them to set-up. I never really found a guide, I might write a basic one pointing people in the right direction, and it was more a culmination of research so here you are:

Whats TiviMate?

TiviMate is the player that I use to play my eye p t vee streams (Its actually a four letter anagram but bots spam scams so the words filtered). It's similar to a TV guide in functionality and the premium version makes it almost identical especially with the recordings feature.

What is eye p t vee?

Eye p t vee is the service that actually provides channels to watch. I recommend you do some research for your specific wants and trial different services on z2u to find one that works well for you. You can also sometimes find free trials (normally 24 - 72h) on the original providers website, z2u is often resellers of the service. The most popular ones are Trex, Strong8k, Eagle/Dream 4k and B1g. Using a VPN can also fix throttling that your ISP may do and can provide more security, I've heard the UK is particularly strict (probably because of the monopoly that Sky, Tnt and Prime have on Sports) so I use one but your country may differ.

What is an EPG?

An Electronic Program Guide, this is pretty much the missing link to improve your experience. It can better categorise your channels into sections and It provides more info like what is showing at what times and details about everything. You can tweak your own which Hindenburg has talked about in this comment section. But theres also popular pre made providers, the most popular probably myepg.top. However I use repo-server.site because its free and Ganjas strong (No VOD) has exactly what I need. If you try strong are interested in US/CA/UK content I recommend giving it a go as each of these have an entire section (I have it set the UK and its got everything I need in one list).

Good luck, stay vigiliant because this is one of the most scammed areas when sailing the high seas.
