Ok so this is unexpected. I took delivery of my eBay-purchased Grundig GS3000 digibox today, got it all set up, and was straight on the phone to SKY to get the old card married to the new STB...but after 8 minutes of queuing in the phone system, I got bored and plugged my viewing card in anyway. And everything seemed to be working. I don't have any premium channels, but I'm fairly sure that MTV and SKY One are not available to Freesat cards...in fact I couldn't find any channels that didn't actually work. So, can anyone explain how this can be?
