YouTube is consistently throttled by Hughesnet disregarding any account setting turning off video throttling. This is easy to prove beyond the shadow of a doubt by testing data rates from other sources and testing the YT videos through other providers. On a Monday morning with high data rate speed tests, I couldn't watch ANY YT videos at even 144p, the lowliest pathetic video res.
Never will understand why people keep posting Tech Support related issues in General Discussion... :-\
That aside, Hughesnet isn't throttling Youtube, if you can prove with out a doubt, please provide your evidence, and not just words. By the way, when streaming, youtube isn't constantly sending you data, they send small short bursts at a few Mbps. Doesn't take much to stream 720p ya know.
You may be experiencing another issue, such as running out of data, or computer/router settings. Hughesnet doesn't throttle it at all.
