A: You probably have configured your Quality Profiles wrong and enabled BR-DISK and didn't add the recommended Custom Profile to help Radarr to block/ignore it. [BR-DISK](/Radarr/Radarr-collection-of-custom-formats/#br-disk){:target="_blank" rel="noopener noreferrer"}
A: If you notice that some movies won't be grabbed because of these size settings, you can provide me proof with a screenshot and the error it shows you when you do an interactive search (non redacted except the indexer/tracker if you want to).
The highest preferred quality you can manually enter is 1 less than the Maximum quality. If you use the slider, the preferred quality can be up to 5 lesser than the Maximum quality.
Make sure you have enabled 'Show Advanced' in Radarr, if you don't see a provision to enter the scores, under the Quality settings.
