Sorry,
All I can suggest is that you get in touch with Melksham Satellites. I had an issue with a foreign box, and they proved invaluable and very helpfull. Do a search on the net and give them a call. (Sorry if this is deemed advertising, not intended, just trying to help)
On a seperate note, has anybody else had a widescreen picture (from Sky) chopped into a narrow one? Seems to happen mainly if watching sport from BBC/ITV through the satelite (CH 101/103). If you watch via the aerial, it's OK (but a naff picture where I live).
Cheers
Splat
