Large file transfer such as copying recorded DVR shows.
The DVR allows to be on the network? Lucky you.
I have everyone stored centrally, all other devices would only access the network storage to play a file directly, so the bandwidth requirement is low. 100mbps is more than enough for a bluray movie.
Anyway, even if 1gbps is rarely useless in a household, we don't know what to expect in 10 years. 10 years ago, we wouldn't have terabytes of media and movies were 720p at best. When you install wiring in walls, you tend to want to use it for a good 10-20 years
