With TorrentRSS you can disable the size check, though that means Sonarr won’t ever know what size the release is.
Support for indexers is added if there are multiple using the same format (we’ve added eztv RSS support and another common one), or if they have an API we can look into adding it, but since they were in Jackett that is usually a good sign and API doesn’t exist. If they were willing to add a Torznab API that’d work as well, but that’s effort on their side.
Thanks markus101 for the details, i understand your point of view.
What is the impact exactly when disabling the size ? If the release name contains the quality like 720p / 1080p, Sonarr should still be able to pickup the correct quality, right ?
Also, is the torrent delay respected using TorrentRSS ?
