Thank you for your post. But, my post actually Is about Samsung TV model UE43Tu7092U. In the TV’s E-Manual and also in KT2ATSCT-2.1.5_EM_KANTS_USA_ENG-US_201020.0.pdf E-Manual, at page 64 Editing Channels is mentioned the possibility to delete a certain channel. But in fact there is not possible to use the functions because is not present in the TV menu Editing Channels.
The mentioned video is about some other TV model.
