Problem was the bandwith was so high at the beginning stream quality was really good but users with low speed connections could not watch without getting buffering all the time. They lowered it drastically and after that it was really worse. They adjusted it a bit and now its ok. Not as good as at the beginning but ok.
I still favor a SD Switch for low speed users and an HD switch for high speed users. @Voyeur House TV will you tell us if its possible?
