Is this a fixed dish?
Where is the dish pointing? 19ºE - 27ºW - or where. If you were on Sky digital, you'll be set to 27ºW and there is a hotbird satellite there too. In fact some Sky programmmes are on Hotbird, as well as some on Astra.
There are other Hotbirds in other places in the sky.- You need to be pointing at Hotbird3 at 13ºE - if you aren't you won't get it.
Dish adjustment requires a digital capable signal strength meter, and a degree of experience. Otherwise you'll be trying for a long time.
According to here, you can get it via Internet too.
but you have to pay.
