I can vouch for Vs5 box, but you do need a dish, I don't own one, but know someone who does, it is pretty good, no HD if I recall, loses signal sometimes due to scrambled, but not for long, not sure why that is though it could be very slow net connection (it needs an internet perma)
Get HD channels not sure about 5/1 i'm afraid? sure if you did a bit of looking you might get one with it! As I said before wiziwig.tv for all sports on the internet. I watched the bellew fight live on my laptop. it was a sky box office premium payment!!
