If TNTSAT receivers do not allow you to edit the chain of DTT (only on a favorites list), they can at least do it for other channels in light of the Astra satellite or other satellites: it is say you can delete or move the stored channels. It does not allow it. In the list of channels you can not delete or move, and favorites can not move either. This device is indicated only if you want the channels of DTT. Good image quality elsewhere. I advise against it if like me you want to watch the numerous channels in light of Astra 19.2 ° or 28.2 ° Astra and others. Also, on my device malfunction to report: the volume on the remote control has no effect on the sound (it works for radios but not for TV channels), so I can adjust the volume that with the TV remote.
