If you are going to do so, please get your facts right , improve your comprehension, and preferably not question that I have a different experience of the product.
I live in a strong DVB-T area and my DishTV T1020 never dropped channels or signal.
The Tivo is marketed and sold to joe public as "it just works" Freeview DVR with superior ease-of use, and added frills like Caspa etc.
Mine doesnt show TV1 and TV2 and is rather noisy. Busy people, old people, small children arent going to be rescanning every day when they want the news on.
They have falsely promised fixes in the past for the dropped channels, so this is their chance to make good.
