Hi Tony,
Many thanks for your reply. We tried changing B/G on the tuning screen, but the up/down arrows didn't seem to change anything when we had it highlighted. We did manage to get our Freeview box to work via the SCART socket, so sanity has been restored ;-)
Still trying to get the analogue tuning to work, although may be short-lived as we head towards the digital age. Having some email back-and-forth with B&O customer care. Slowly making progress - we managed to add "TUNE" to the list of options on the Beo4 display (I can explain how to do this if anyone is interested). In theory, having selected "TUNE", pressing "Go" then the yellow button should switch to PAL I, but this doesn't seem to work - maybe we don't have the TV in the correct mode. We're awaiting another reply from them. If we do manage to get it to work, I'll drop a note back in case anyone else has the same question.
Kind regards,
Chris
