As discussed here, I was wondering if there are plans to "build a filter in so only non-sample media files are added to the history list". Sonarr does not handle all the miscellaneous files correctly and interprets every file download by the NZB as a duplicate download of the intended video. I didn't have this issue when I used NZBGet but that program didn't max out my connection and Newsbin is much more efficient and user friendly. So far I've just implemented a NZB filter that bans all files less than 200 MB but I've yet to test it.
I'm also having an issue where the time left is always "6.04:38:37" for each download and it never changes.
