The only issue I had before adding DB to Streamio was sometimes the streams would lag. Once I got DB on there I never had that problem. But obviously that’s also dependent on other factors like how fast your connection is and how many seeds the torrent have. So you could be just fine without DB. But if you do have issues, I can definitely recommend adding it, especially since it’s so cheap.

Depending on where you live. It could be a issue that without db you’re just straight up torrenting and may need a VPN to keep from getting copyright notices. Also it will probably buffer a lot without having the db cache.

Yep, you can. I did it that way for about a month before i got a debrid account. The selection isn’t as great since some torrents are dead and since you’re torrenting you’re at the mercy of the seeders. Also you should be using a VPN while you stream so you don’t get a whiny email from your ISP. But i had no trouble watching popular stuff without a db account.
