It’s not a transcoding power issue. It’s a UI consistency and usability issue. With every device having a slightly different UI, with some apps having issues if playing back natively and some needing transcoding, the experience is inconsistent and frankly doesn’t pass the “wife acceptance factor” test, or the “let your friends use it without needing to handhold them through regular troubleshooting for their particular device” test.

I still don’t use Plex and exclusively use Jellyfin, but it’s still a hard sell to non technical users. Plex has much more polish.

It is……if you use a computer. Their AppleTV app still looks like some random coder’s pet project with random playback issues.
