Oh ok, the first thing that comes to my mind is Kodi. Depending your pc it might be a bit slow but that should work.

Edit: are you on linux or windows? If windows, you should really consider linux. Old pc comes back to life with linux as it needs way less ressources than windows

I guess you meant something to act as a remote desktop? Something lightweight better than a remote desktop for your use case is to setup a FTP server or a samba share. You will then use some media player client to read from there

There is many different instances, maybe try another one

Haven’t used it much but as another option, you could try some firefox addon like libredirect so it will open some redlib instance.

You can go to Annas and search “piracy”. Not sure how much materials you will get but there will be some

I don’t know about jailbreak, but you can sideload games/apps. Will send a link in mp

It already exists for quest (vr head set) which is android base, so I guess we will see one for phone at some point.

Check brave history and you will see the amount of controversies they have. I personally wouldn’t believe anything Brave says.

Cool, enjoy

My guess is that your issue is from torrentio, I don’t use it but heard a lot recently about instability. You could try comet instead of others.

You already had some good advices but something I haven’t seen mentioned. If you use Kodi (and probably a couple others media player), you could use some sub plugin like open subtitle (forgot other names) to fetch subtitles on the fly when you will play video. It can be hit or miss at first, but subtitles name are like release name (title, quality, release group). So if you often encounter a release group that do your sub language. Try to download video from same release group, so you will have better chance that audio/sub sync properly.

This apart, +1 for private tracker as already mentioned, you may need some searching to find one but worth it.
