Thanks for that, it confirms what I thought I had later found via Google, but it wasn't very clear.
Had the DB on Pro7 most of the day but no indication from the amp that it was decoding, then they announced a film at 7:15 in Dolby Stereo but it still didn't show - but then I twigged, you have to select the AC3 audio specifically using the remote's audio button.
Then the amp decoder kicks in, works great via the optical connector. The film was 'The Mean Machine', great surround sound, but watching Vinny Jones appear to speak in German was bizarre to say the least.
