I'm signed up to 'sky world' and some of the movies are broadcast in 5.1 i believe. I've got the Amstrad DRX 400 didi box, there is a cover on the back panel that says 'digital interface' that is screwed down. The question is, how is it possible to get 5.1 from a digi box? My Tosh 32ZP18Q has an optical socket and a coaxal socket. Best Regards Rich Tee.
