I've used several different android boxes for iptv as well as other streaming apk's.
For iptv, I've always used STB emulator, and iptv smarters pro.
The only issue with that, is you can't easily access all the features that a Set Top Box has for iptv. Most notably, with the remote options.
Now my issue with Set Top Boxes, is everyone I've come across, is either impossible (or difficult) to sideload other apps onto it.
So what Set Top Box/Android hybrid would you recommend, that allows the best of both worlds? One that easily allows adding free streaming apk's while having the best iptv experience possible?
