1. Jellyseer is what I use, also allows others to request stuff
2. I download via torrents, automated with the *arr suite
3. My seedbox, fast speeds also help with my ratio
4. Jellyfin, just because i prefeer FOSS
5. Jellyfin covers that, if i happen do delete some show then Jellyseer still remembers if i finished it or was only partially done

Lots of seedbox providers offer all these tools with their boxes so you dont need to host anything

check the megathread in the sidebar or fmhy

It doesnt seem like its fake but i have never heard of that site before, personally i use predb.net and xrel

I have been using ultra for over a year now and dont have the issue you are talking about. How many seeds/peers do the torrents have? Might just be that there arent a lot of people dling what you are seeding

hawke.uno has x265 stuff, they had open signups recently but idk if they still are

cs.rin.ru is probably your best bet to find those, but you will have too look for each game separately

By taking a look at the megathread and using one of the many sites linked there to obtain the desired content

Dont think there is any dedicated tracker for 4k stuff, you might find some here and there. I know that immortuos has some 4k movies and i think TV and you can probably get some on other trackers by requesting it.

Besides what the other commenter said you can probably download just the update from dodi and update your current install

Im in WOT and tbh dont really remember how i got in, i just checked everyone that jackett had amrked as german and tried to apply an noticed that i had an account there, maxbe open signups. You can probably get Invites to other german ones by building ratio on others like TL, RED etc and have a member from there give you one

Idk how stremio and torrentio work or if you can add other torrwnt sites to it similar to *arr apps but if you can then try to get into a few german torrent trackers, most lf them are private but once your in one you can get a lot of stuff there im in one myself and all the big shows and movies are no problem

As others have stated that its game dependent, if you want to get some that work online check out online-fix.me or cs.rin.ru
