I subscribe to Hulu, Netflix, smoothstreams and soon Italian IPTV. Occasionally cast but doesn't really matter.
I need another box and Currently using Xiaomi mi box along with IPTV APK. Should I continue this route or buy something along dreamlink or similar.
That's all I use it for.
Do all IPTV devices have EPG?
I don't think anyone but yourself can answer this. If it's just for a specific apk, pretty much any cheap Android box will work just fine.
If it's just for iptv, a mag or similar works well for most people if you want everything working out of the box with good epg, timeshifting, vod type stuff.
This question is asked pretty much ever single day, so make sure you watch the video reviews over in the sticky at /r/iptvgta to see what the different interfaces are like and see what best suits your needs.
Since you're using Netflix your only option is a Xiaomi as Netflix is disabling their app in rooted/unofficial devices. If you weren't I would suggest a cheap chinese box with a community firmware.
what is Italian IPTV....I think my mom would like this...
Try perfect player for the Mibox, is on the play store. Is awesome for IPTV
