corocoro I have the same issue, I just got a job again and I'm all of a sudden short 8 hours of leisure time on weekdays, and when I get home I want my content there waiting for me, not having to do the manual dance each time I get home, then wait for it to download.
I've had some success and some failures;
The good part: jDownloader nightly has JDFeedMe inbuilt, and it works, though it's a bit crude compared to uTorrent's RSS features, it allows you to input an RSS feed to download items from and you can filter (very basic filtering, allows you to set "words" is has to have, and can't have) it, but it doesn't have the "smart episode filter" uTorrent does, thus if you get a duplicate entry for a show it downloads both, this means you need to either get curated RSS feeds or filter them, here is where I've ran into issues, it's also lacking uTorrent's feature that allows you to set the download location on a per feed/per filter basis, thus all hits on your feeds will go into the default folder what ever that is, and you'll have to move them yourself or use a tool to move them if you like me organize your media, not just dump all the video files into the same folder.
I've tried to filter entries in various ways, the primary issue so far is that I can't find a good source of anime RSS feeds, anime-sharing doesn't include the links of items in the RSS feeds, you need to open the page proper, also there isn't a way to get an RSS feed for new posts in a thread, just new threads on a forum it seems, which isn't exactly useful for this.
The subscribe to thread feature might possibly offer a solution, if I can figure out a way to convert incoming emails into an RSS feed, since the email contains the file links.
I've had some success using the RSS feeds from FilesTube searches which has a fairly extensive search feature that lets you narrow down your results, but you still get duplicate entries, this is where I tried to use yahoo pipes to try and filter the search's feed further using the "unique" feature, which kinda works but all these steps makes the total process very unstable and prone to going sideways.
Best solution I can come up with for now: subscribed thread emails getting converted to an RSS feed and then piped into JDFeedMe, should work nicely, if I can figure out the email -> rss part, haven't had time to look into that yet.
