Thanks. I sent some feedback about the RSS feed, we'll see if it gets updated anytime soon.
One thing that I did notice. When rutorrent catches the RSS feed match, and the torrent then shows with just the hash name in the list, like I said, I can add the tracker and the download then starts. One problem however, when the download starts, it writes directly to my "inprocess" folder, not with a sub folder. So it should be: /rtorrent_path/inprocess/showname.s08e43.../showname.mkv, but instead it becomes /rtorrent_path/inprocess/showname.mkv. This then causes a problem because my .rtorrent.rc has the command to move the parent folder of a completed download, so rtorrent then moves my entire inprocess folder, screwing up every other downloading torrent.
Not sure if that's rutorrent's problem or rtorrent. Since I can't manually change a torrent in rtorrent to add a tracker, I can't test that without using rutorrent.
Thanks again for all of your help.
EDIT: I also noticed the above behavior if I used the Retrackers plugin. The torrent will automatically get the trackers that I want, but the folder name is removed from the path as if the "Don't add torrent's name to path" check box is chosen.
