I mostly agree - if TV is still really watched, go ahead, but make sure that network cabling (double sockets in every room, more in the living room...) is not skimped on for that purpose. Sat-over-ip works well for me with the high-quality converters - but is only "used" once a year. Since I get it from the neighboring house, that’s not so bad, otherwise I would have been annoyed.
What I would like to add: don’t block valuable photovoltaic space on the roof with the dish. The dish is much better placed on the facade. It is better protected from wind and weather and easier to access if something happens.
