'Add download link via itorrents.org' not work...
can you add other mode to download a torrent from corsaro nero? magnet or idope or torrage?
thanx

you get the magnet by default, that's the U symbol when you get results from the dashboard searches of ilcorsaronero.
the itorrents link is optional, (thats the downlink symbol), and usually the itorrents.org site has most links available within 4 hours or so after the publishing date, but its not guaranteed.
if you dont want to see those links then untick the checkbox from the dashboard indexer config when you edit with the wrench icon the ilcorsaronero indexer.

I do not understand why then when radarr does a search and find the torrent on 'corsaro nero', it does not add it to my 'rutorrent' downloader. for all the other trackers it works correctly.

@kaso17 ilcorsaronero only generates a torznab download link if the .itorrent.org checkbox is ticked.
the magnet link is always generated, but is this link a torznab attribute? if not, then that might explain why radarr wont pick it up. Am I right?

Disable 'Add download link via itorrents.org', it's unreliable.
@garfield69 if no download link is available the magnet link will be used instead.
radarr/sonarr should be able to handle it.

I tried to remove the check, but unfortunately the downloads via radarr to the 'corsaro nero' are not sent to my client download (rutorrent).
If I manually glue the magnet link on utorrent it works, but it does not automatically.

then please check the radarr/rutorrent logs.
