That is the typical misunderstanding in the upload process new uploaders have on private trackers (I had it too, when doing my first own torrent).
What is needed to be downloaded, is only the small .torrent file and not the big shared data file (here mostly a movie file). First time uploaders go fast, download the .torrent file and add it to the torrent client, which then will try to download the data file (movie), which won't work, even with good ratio.
The download of the .torrent file is required, because at download the personal secrete passkey is added into the .torrents file information. That passkey is missing in the originally created and uploaded .torrent file.
The "trick" is to make sure the torrent client finds the big data file (or the folder with the files) from which the torrent had been created originally when adding the .torrent file to "download". Then it will check the existing file, which should match, and start seeding instead of trying to download.
There exist two principles to achieve that:
1/ Copy the big data files (or folder) into the default download directory of the torrent client before you add the downloaded .torrent file to it. This method is quite universal.
2/ With the right UI settings (e.g. µTorrent's and BitTorrents default out of the box settings) good torrent clients show a window with the torrent's files and the target download directory when adding a torrent. Here the target directory needs to be changed to the directory where the fie (or folder) from which the torrent was created is located.
I see the opening poster has managed to seed his upload, so this seems be solved and that can explain as well his better share ratio.
