Disclaimer: I do not have access to Apple TV.

I tried to compile the ways that are said to work.
If they don’t work it most likely means the video no longer available, which means SF can’t download it

First, there is a link in this community, post #2, that has the instructions. (https://forum.dvdfab.cn/d/472014-7022-downloading-moviesshows-purchased-via-apple)

This next info comes right from Wilson, the StreamFab & MusicFab manager.

Guide: How to Download Apple TV Purchased Movies with StreamFab? 2026 New Release
You “own” your Apple TV movies? Not if they delist them. Here’s how to actually keep what you paid for.

You “buy” a movie on a digital storefront, the licensing deal expires, and suddenly that film vanishes from your library. Apple is better than most, but they aren’t immune.

I spent my Tuesday morning running some tests on our latest release. Our devs have been working overtime to ship this—specifically the new feature for downloading purchased Apple TV content. This wasn’t just a “task” on a board. We really hope this update shows that we’re listening. Here is the no-BS walkthrough on how to use StreamFab to pull your purchased Apple TV content before it disappears.

Get into the Apple TV Module
Open StreamFab and hit the Apple TV icon under VIP Services. Don’t bother searching through the generic “Popular sites” list; go straight to the source.
Sign In
Log into your account. We use an internal browser to handle the handshake. It’s the only way to let the platform know you actually have the rights to the file.
The Search Workaround
Here’s a pro tip: Sometimes the internal search is finicky. If you search for something like Godzilla x Kong and it says “isn’t available”, don’t panic.

Click “Top Results”.If that still fails, find the URL in a regular browser (like Chrome or Safari), strip out the country code (the /us/ or /jp/ part), and paste that direct link into StreamFab.

Analyze and Strip DRM
Once you click the video, StreamFab starts “analyzing”. This isn’t just loading the page—it’s identifying the manifest files and the encryption keys.
Choose Your Quality (The Important Part)
This is where the platform tries to throttle you. Don’t let them.

Video: Select H265 if you want to save space without sacrificing clarity. If you’ve got the hardware, toggle Dolby Vision or HDR10+.

Resolution: Don’t settle for 720p. If the 2160p (4K) stream is available, take it.

Audio: Grab the Atmos or EAC3 tracks. Anything less is just a waste of your speakers.

Google search:

For example, the search result URL is [https://tv.apple.com/us/movie/godzilla-x-kong-the-new-empire/umc.cmc.1bs3cq39p3x7de4j8kq8l82wz]

you can delete or edit the country code in the URL, and paste it to StreamFab, such as:

[https://tv.apple.com/movie/godzilla-x-kong-the-new-empire/umc.cmc.1bs3cq39p3x7de4j8kq8l82wz]

If you have the access to this purchased movie, StreamFab can analyze it.

Execute
Hit “Download Now”. You’ll see the progress in the “Downloading” tab. In my test, a 4K feature was pulling at around 1.54 MB/s—not NASA speeds, but solid enough for a stable, high-bitrate rip.

Hope this info helps.
