Hello RDBrown,
We're sorry to hear you are not happy with your HughesNet service. After reviewing your account, I was able to locate the call recording for 8/31/17 where our Video Data Saver was discussed. The agent explains Video Data Saver, and how it works to set streaming video to Standard Definition to consume less data.
Since you are familiar with reading manuals and how-to's online, I believe our Help/FAQ section (under Support in the bar at the top of this page) would be very useful to you. Here is one regarding how Video Data Saver works - http://support.hughesnet.com/support-articles/what-is-video-data-saver
Regarding data limits, I recommend reading the accepted solution from one of our customers who breaks it down very well - https://community.hughesnet.com/t5/Tech-Support/unlimited-access/m-p/42583
Thank you,
Amanda
