Hi im new to this forum, so apologies if this topic has been hashed out before. Reason I'm querying how much bandwidth Netflix uses up for say, a typical 2hr movie, is that we seem to have maxed out my Orcon fibre account to the tune of 90Gb in a week, and have only watched Netflix a few times including our usual internet use (FB, email etc). No gaming or torrent downloading of a serious nature. We do have a Chromecast although i turn it off at the wall each night. So how can we possibly be using up ~10Gb of data per day, it seems extreme.

Today, in a bid to get a handle on this, i changed the password so that Chromecast can't connect itself, and have been barely using the web, yet still the Orcon account page is saying we have used 2.5Gb! Are Orcon somehow misinterpreting our usage, or overcharging me in terms of data? How can i check this? Any help or advice is much appreciated.

Matt
