If you are on a 10/50 gb per month plan, and you are trying to stream a HD quality movie, regardless if it is through Xbox/playstation/Netflix/Roku, HD streaming a SINGLE 2 hour movie could burn through not always but as high as 4-5 GB of data (I have even read up to 7gb). So, that 10gb plan and one 2 hour movie, well, half your monthly data is going to get used up. Hope this helps. Somewhere, at least with Netflix, you can set your streaming quality to low. I found after a google search, we can enter a series of remote control key presses on our Roku remote and change the streaming of our Roku from 3.5 mbps, down to 0.3 mbps. Huge difference in data usage, if you don't mind a slight change in the picture quality. We hardly notice a difference. Its like watching a standard movie vs. a bluray movie.
When your talking a 15 mbps or higher download speed with hughesnet, one can do the math.
Your downloading 15 mega bits per second. Thats 1.875 mega bytes a second. There is 1,024 of those in one gigabyte. 1,024/1.875 = 546/60seconds.... That's just over 9 minutes to download one gig of data. Wow, data can go quick! So for the sake of argument one movie at 4 gigs, 9x4=36 minutes. So, just over a half an hour and you burned through almost half of your data.
Hope this is correct? I'm no math wiz, pulled this info off of google....
Hope this helps.
