We've been subscribing to Sky Digital for just over a year and took advantage of the "Free Dish & Digibox" offer and got one of the bog standard digiboxes (Grundig - not sure which model) I'm now in the process of upgrading my Home Cinema kit and have just purchased a Denon AVR3802. To my surprise, I see that there is no digital audio output on the digibox. (I don't subscribe to Sky+ ) Is it possible for me to purchase a new digibox with optical output and be able to just switch it with the original one? If so, is it worth doing this to be able to connect it to a optical input on the Denon AVR - would I be able to hear 5.1 on any suitable broadcasts even if I'm not subscribed to Sky+? Sorry if these are stupid questions.....I'm not well versed in the tecchie side of digital TV! Thanks for your help, Adele.
