You would get it to work by buying a sat box called a Skybox F3/F5 and taking something out called an Nline in the UK. Just make sure you have a dish pointing at Astra 19E which I think is the correct Sat for that network. You can get the box from Ebay, the N-line? give me your email address and I will forward you to a source.
I am looking for a Polish speaking TV technician in the Manchester area who could fix my mum's decoder. She receives Polonia TV on the decoder and has a subscription, but recently the sound disappeared although the picture is fine. Sound on UK channels is also OK.
