Nvidia Shield was never really rated as the best for IPTV
The thing was that when the Sheild was first seen on the market, there was pretty much no such thing as a dedicated iptv box , like that Dreamlink T3
The mag boxes may have been the only reel choice for a dedicated IPTV box (in western Hemisphere anyway).
But with the correct application any Android will do. The Nvidia Shield is a very powerful Android so that is why it may have been considered the best. But truthfully it is all in the application at how good the experience is with IPTV directly.
And of course with that Sheild being so powerful, will always help when it comes to loading speeds and etc
You could run IPTV (NFPS) thru the Nvidia in a few different ways (different applications).
- IPTVXtra created and maintained by kens/Shooty from here at iptvtalk.
- STB EMU, run thru Kodi or sideloaded from an .apk file version of the app.
- Kokaleka TV app, sideloaded from an .apk file as well.
The Nvidia will be capable of sideloading these apps thru their .apk carriers or using Kodi and its abilities to run apps
