See, this is what I'm talking about. Sounds to me like that's not a simple 683mb movie. In fact if it were, you should have no problem streaming even in FAP.
Yes congestion maybe a factor but when you are paying so much for so little shouldn’t that be factored in with service? Comcast and AT&T doesn’t suffer from this.
What you're paying for is the sunk cost, technology, real estate, and overhead required to bring a 2-way satellite signal to your house. The costs are mind boggling. You really can't compare it to the cost involved in terrestrial (Comcast and AT&T) which is nothing more than a server and some cabling (or fiber) from 3-5 miles away, and not a whole lot of overhead at all - we're talking pennies on the dollar.
Next, consider that satellite has a finite amount of end-user spot beams (~97 are used), with a finite amount of bandwidth per spot beam. You're sharing that beam with others over an area covering a few hundred miles in either direction, not just a handful of expandable servers for a single neighborhood.
Each spot beam, is then merged with signals from other spot beams, and channelled through one of about 17 ground stations matrixed about the west coast, which are then connected to an upstream provider on the internet.
The key here is 'finite' because you can't just call a tech, fly up to the satellite and add a new beam like you can with a terrestrial service.
So what you do, whatever others are doing on your router, the same beam you're on, and even the ground station you share adversely affects the congestion that you see. I think we did the math on here once and came to the conclusion that the resource demands created by only 40 people on the same beam simultaneously watching an HD movie could feasibly shut the whole beam down.
I'm not even including the impact that 500ms latency (satellite: ~72k miles vs. terrestrial 3-5 miles) has on trying to do resource intense activities such as streaming.
You're right, Comcast and AT&T don't suffer from this, but they're not even close to being the same thing.
Thanks. I had hoped it would help you and others understand.
