Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Bruno.
While there are some options for dtv integration, they really aren't applicable. This is a very old and discontinued model, it is no longer supported by tivo, and if it is not activated already, it cannot be activated, so it really has no use at this point.
Your best option would be to resell the unit on ebay or amazon to someone that may need to use it for parts, and start over with a new model.
