I have an iMac (recent) which is connected through Ethernet
Movies/programs are loaded into iTunes
Apple TV connected through wifi to both the iMac (iTunes) and to the internet
Apple TV connected through HDMI to the TV
There is a Prime Video active app on both the TV and Apple TV. Ditto all the standard apps like SBS On Demand, ABC iView.
I don’t have Netflix. SBS On Demand keeps me busy enough. I do have Amazon Prime Video ($7 a month)
Regrettably this year, MLB.tv app no longer works on LG OS, so I have to watch baseball through the Apple TV box.
The Apple TV is the version before the 4K version.
I don’t have a laptop (except the old man’s 5 year old Dell) which I’ll dispose of once his estate is finally cleared - certainly after tax time this year. It won’t be going near the TV. It’s pretty crap. I just have no need for a laptop.
There may well be, i.e. there is but don’t ask questions, a copy of Bosch Series 5 on iTunes…so it’s not important from a “watching it” POV, but that was only done after Amazon pulled the series.
PS the TV and the computer are in different rooms.
