Cloning via USB works great, and with the open source software ChanSort also perfectly to the transmitter to adjust. (Especially if the cable operators once again surrounded all new tuning, load it into the software store, reference list (from earlier) and already all the channels are again sorted the same. (From the TV via USB).
It is a pity that Samsung is not capable of self-programming as a tool, and is also a pity that the cloning of channels of TV to TV is not possible if the same model is not exactly. This is an absurdity, therefore only 4 stars. Because frequencies and transmitter assignment is for all TV's still the same. Enough already, if you change the country that the channel list is not satisfactory. Not that you ever will change countries, only those limitations are inexplicable for me.
Otherwise, you can also lock the TV, so that no changes can be made. Have about 20 of them in action, so far there has been no error.
