Cannot play any iTunes movies on my Hackintosh

Hello! The title is pretty self-explanatory - can't play bought movies -, but, anyway. My GPU is NVIDIA GeForce 9800, and it's so old that I all I had to do for it to work is just toggle the checkbox Inject NVIDIA in Clover Configurator. All the other hardware isn't much outstanding: Gigabyte B150M-D2V; Intel Pentium G4560; Monitors: Samsung SyncMaster P2270 and Acer AL1916W

I've also tried to check if the playback from Apple Music's videos works, and, yes, it does. VDADecoderChecker for 10.12 from https://github.com/vit9696/Shiki/blob/master/Manual/FAQ.ru.md reports this: https://pastebin.com/Ha1GeFPS (tl;dr: VDADecoderCreate failed. err: -12473)

Shiki.kext (2.2.0) placed to /EFI/EFI/CLOVER/kexts/Other didn't help me either. As well as these commands: defaults write com.apple.AppleGVA forceNV -boolean yes defaults delete com.apple.coremedia defaults delete com.apple.AppleGVA sudo rm -rf /Users/Shared/SC\ Info sudo defaults delete com.apple.coremedia sudo defaults delete com.apple.AppleGVA

P.S. I wonder if it's related to the fact that some images don't properly load up in Chrome, such as photos (sometimes) on VK.com (example https://photos.app.goo.gl/j3N81Wcdgl3HSD743) and play button on youtube when in fullscreen mode (now it works but nah dunno)
