I don't care if it costs $3 or $3000, if I buy something from you, it better work or I expect my money back. Especially, if everybody who is subscribing is having the same difficulties.
I am a communications guy. I have talked to airplanes 10,000 miles from me during all sorts of weather conditions and propagation. I have operated radios located on the other side of the world through phone lines, microwaves, underwater cables, radio circuits and satellites. It may have taken some adjustments to my equipment and antennas, but I usually got it to work. If it didn't work, I could tell with great confidence and accuracy whether it was MY problem or YOURS.
Excuses are for people who can't reliably provide a product to their customers. You can't expect the reliability of a Rolls Royce if your equipment and setup is that of a Ford Pinto. When you go into an establishment to run a PPV, you can't rely solely on them to provide adequate bandwidth. You have to test it first. If they don't have it, you have to provide your own and pay for it. If you can't make a profit and provide the service, then don't offer your stream.
