How much data does it use to stream a TV show?

How much data does it use to stream a TV show, say Masterchef on BBC iPlayer, or a 42-minute programme on Netflix?

This is straight from Netflix... took me a full 20 seconds to find :p

Watching Netflix uses about 1 GB of data per hour for each stream of standard definition video, and up to 3 GB per hour for each stream of HD video.

I don't know if that is more, less or equal to what the other dumb-downers use...

Here's another one from a Verizon forum:

Good quality (up to 0.3 GB per hour)
Better quality (up to 0.7 GB per hour)
Best quality (up to 1 GB per hour, or up to 2.3 GB per hour for HD)


Interestingly, you use more data on 4G than on 3G!!!

" Why wouldn't the data be the same for 3G and 4G? Just different speeds. But wouldn't the same movie of the same length be the same data?

If you download a 1GB file over 3G and 4G it's still the same 1GB file."
Not the way Netflix works, it's not a static file size. They raise and lower the quality based on bandwith. On 4G, you could have bandwith for HD if available, that can run 1-2GB/hr. This is why they let you choose the upper limit of bandwith use.
