Rented movie on laptop, cannot get to Apple TV
I rented but did not watch a movie via iTunes on my Macbook Pro. I thought it would show up automatically under "Movies" in Apple TV, but it did not, I guess because it downloaded to the laptop.
The rental shows up under "This Computer." I thought I would be able to see it under "Computers" on the Apple TV, but it won't show up.
My old iMac, also running 10.10.4, will show up on the Apple TV. The settings on iTunes on both computers re: sharing is the same. But if the old iMac is off, no computers show up under Apple TV's "computer tab. I'm supposed to turn on home sharing in iTunes, the Apple TV tells me. I assume this means to select the "Share my library on my local network" option under Preferences. Sure would make more sense if that preference were called "home sharing."
It just occurred to me that I might be able to get the rental to show up in iTunes on the old Mac. But really, I'd just like to get it to work with the laptop.
I've tried restarting all devices; restarting iTunes; renaming my laptop under "sharing"; signing out and in of Apple TV.
So I'm stumped. 10.10.4 on both iMac and Macbook Pro, and latest OS upgrade on the latest model of Apple TV.
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
