Strongly agree with this. Plex’s DVR functionality was very shaky to start with and I switched to using Channels, which to be honest is better than anything else at being a DVR. But it’s $60 a year and Plex costs me nothing (because I bought a lifetime membership years ago) so I switched back.

Every time I tried Jellyfin the DVR stuff had weird problems and the client apps were notably inferior. In fairness I haven’t checked in a while.
