Hi.. just my 2 cents. Maybe this will help some people in here. I am now using TPK Iptv ..easy to setup..have only 10mbps maxis fiber. Streaming is good. All sports channel and movies is there.
But I don't believe in this discussion..no one have ever mention about using a vpn.. (tips: please avoid free vpn and paid vpn that cost a lot, sometimes they are just fake)

I have tested without a vpn..channel will always buffer. It will buffer heavily while on peak hour. Our ISP will deny this 'throttling' things but its really is there. I can assure you that this is not hardware decoder issue, streaming server issue or while MU is playing..

I have two android box, one is old 512mb ram and 2nd one with 2gb ram. Both device tested with this setting and works fine!
I am not promoting any service here..this is what I personally use..

1. Subscribe to paid IPTV, any, or use free IPTV app (also works)
2. Subscribe to any SSH VPN that support Open VPN (its easy & cheap!! and reliable) fast speed even for playing games. You just need to know which server to subscribe.
3. Let's Openvpn run in the background (set auto connect when device restart). And all the channel will run smoothly.. imagine I only have 10mbps but can watch 1080 fhd channel while my two kids watching youtube! (Both have their own ipad

I just dont want to reveal too much here and maybe you guys know why.
I am now living happily without satellite subscription and my monthly bills for iptv and vpn is under RM30..
