Settings -> Indexers -> Turn on advanced settings.
Then add X265 and HEVC to must not contain.
Also check the profile your series have, the default setting is stored in your browser, so you might have been adding them with the wrong settings because the default got reset.
Easiest way is Series -> Series Editor for bulk check or change.
Yup. Didn’t fix it. I came home today from doing errands to find that 3 shows had 10+ copies downloaded. I’ve figured out what seems to be the problem.
Sonarr see’s that a new episode is release, searches based on my criteria, downloads the best option. It completes the download, but doesn’t copy it over, so it keeps cycling the requests and keeps adding them because it doesn’t see that it’s actually in the show folder.
If Sonarr isn’t supposed to be moving files, make sure Completed Download Handling (CDH) is disabled. Disabling CDH will ensure stricter duplicate checking is performed.
