streaming!?

OK I admit to being technology challenged! We live out and get puter reception thru Verizon's little box that sits in the window sill. We paid for a streaming of the big finals roping in Vegas 2 of the grandkids, and dad roping there. So it come on , and the footage stops and rns a couple seconds, stops, we miss half of the runs.
Was the problem out Verizon box or the people at Vegas doing this streaming??

I also wonder bout Netflix. I had it 10 years ago and they mailed me the DVDs. Now I guess it is streamed? I have to pay for the puter gig a bite for this no doubt??

Sorry I am so dense. ( Wife says not dense, rocks are dense, I am just dumber than a whole box of rocks!)
