unifi does not offer astro iptiv.
u can check if u can dump unifi and change to maxis which does astro iptv - possible in most areas.

u r used to astro and primarily watch live sports.
the simplest and cheapest solution for yr case is to get a mibox (make sure u get the right one).
u use astrogo, an app... but u must have id/pw from a subscriber - u get what he gets.
astrogo used to be crap but has improved - many channels in HD now.
read, ask mibox users here:

or ask general box questions here:

yr old q3 cannot run astrogo, forget it.
there are other boxes that can do that too but will cost more, some a lot more.
of course, these boxes can do more than just one app.

cloudtv is pretty good, been around for a long time.. but the subscription is too high, imo.
u can try other interesting/good apps as discussed by users here:

if new to such things, a new world is waiting 4 u.
if u have 30mbps or higher, u can get a lot of good stuff without paying or paying too much.
of course, if u do not want to get hands dirty, no time... u pay.
