If it's the channel I'm thinking of, they just restream snooker matches. Sometimes it's the best way to view particular matches if you don't have a more direct path or missed the original stream/broadcast.
I always go to Youtube. I just search via the tournament and name of Players such as ‘Snooker Masters 2021 Higgins Yan‘. Somebody in Asia will usually have a session posted as soon as It’s finished.
I prefer to watch via Youtube. With the time zone difference, I can pick and choose matches, parts of matches, etc and watch at my convenience. I like to pause at times, choose a shot, then restart and see what shot was actually used.
if I had had Youtube 50 years ago I’d likely have Made it to about 380 in the rankings instead of 395.
