Thanks for your tips.
I am looking for information on various forums, but for now I have not found a valid ToolOPT6_Energy / Country code for my model with the option DVR ON. I don't want to make random attempts to avoid losing functionality.
I think that a specific number must be added to the ToolOPT6_Energy / Country code based on the function or functions to be enabled.
In the meantime I tried to change the country to Estonia, but the new channel numbering list does not correspond to Italy.
