It is, you just gotta find the right sources. Im on multiple trackers that focus on german dubs and can get most of the stuff i want. Everything else is just a request away.
WOT, TFA, ST-Tracker, Torrent-explosive, immortous are some good ones but they are provate. There arent really any public sites but getting into the private ones isnt hard. I might be able to send you an invite to one or two ot them if i have any, shoot me a dm if you want one.
Do the movies on those trackers typically include the english audio as well? Personally I prefer watching movies in the original language but if I want to make content accessible for my family I would need the german audio
From my experience yes, most releases include German and English often with subs. I prefer English dubs over german ones most of the time but a lot of family members want the German ones so I look out for releases that include both. Try and look for a "DL" before the source, like Movie.Year.German.DL.WEB-DL....
Prowlarr has some listed and once you are in some of the ones with more aktive forums you can find a some more. But i agree it is a lot harder to find german ones.
Torrenting in Germany can cost you hundreds to thousands if you get caught (And they do look for people doing so). Streaming on the other hand is barely worth a fine.
