Quality settings and behavior
A lot of websites provide multiple possible media qualities.
Every JDownloader plugin may behave differently but most of all plugins' default behavior is to either add the best quality only or add all possible qualities.
Many plugins provide quality settings which you can find in the Plugin Settings.
If a plugin does not provide settings but nevertheless returns multiple qualities, you can use Linkgrabber filters to easily filter all items that you don't want.
See Settings -> Linkgrabber filter
