I have the 525 and an Amstrad Sky Box and a Sony TV. Try as I might I just cannot get it all to work properly. I managed to get all the channels showing on the TV guide including all the Sky ones. The first four (terrestrial) all showed up in the little view box and played OK but when I scrolled down to the others - channel 5 onwards - all I got in the little box was the channel grid and the most awful noise. I assume I have it all connected properly but I have to say the manual may have been in Swahili for all the good it did me - a novice and technical illiterate! I reset it all today to factory setup and tried to do it again - on Easy set up (P 24 in manual) when it got to step 4 and auto tuner preset it managed to detect 11 channels after many minutes but I don't know if I selected the right options after that. Is there anyone out there who has the same set up who can detail for me in very simple terms how it should be connected and any ideas where I may have gone wrong.
