I've just installed a friend's JU series Samsung TV and was very impressed with it's features.
With just the one device he now has
Netflix (US)
All UK smart hub apps including BBC iPLayer, ITV, All4 etc
NZ Freeview channels (in HD where available)
Built in 2 tuner PVR with excellent grid based HD EPG
Ability to record from EPG (including series link) As easy to use as MySky or Tivo. (external HDD required)
But here's the kicker...
FreeviewPlus works perfectly. ie he has direct access to NZ on Demand channels from the EPG (despite smart hub country being set to UK)
Only change from MySky setup was installing UHF aerial and Unotelly.
The Samsung JU series has the new Tizen OS so I presume the lower end J series would work just as well.
