Re: "Rented and downloaded movie will not play" "Twice now, I have rented a movie through Apple TV and downloaded it, so that I can watch it later, offline and it does not play."
Thank you for your post to this (user-to-user) community, and for including the details we need.
Am no expert in this area, yet your post certainly deserves some response.
I take it you are signed in to the Apple TV app with your Apple Account and password:
if this is not where you started already :Apple support have an article online (link below) that may be helpful,

See what to do: If you can't watch or stream movies and TV shows in the Apple TV app - Apple Support
Eg: says:
"If the movie or TV show won't start playing
After each step, try to stream or download the movie or TV show again.
- Check the System Status page for service interruptions or check a third-party provider's website for any interruptions. If there are service interruptions, try to stream or watch the video later.
- If you're having trouble signing in to your Apple Account, you can reset your Apple Account password or learn how to get a verification code and sign in with two-factor authentication.
- If your cellular connection is poor, connect to Wi-Fi instead.* Streaming HD content requires 8 Mbit/s or faster. Slower tiers of Wi-Fi connections might not be fast enough to stream HD video content.
- Try watching on a different device using the same Wi-Fi or cellular connection. If it doesn't work, contact your internet service provider to see if there's an issue with your network.
- If other people are using Apple TV+ or Apple TV channels, make sure it doesn't exceed the limits for streaming on multiple devices." (There's also more info. in the above article.)
