FWIW I had Sky+ installed this week and as a result I had problems with the learning function on the Denon remote using the DBS (Digital Broadcast Satellite) source for Sky. DBS is what I had used for my old Digibox and worked fine except that I couldn't get the "SKY" button to be learnt on the Denon remote. With the Sky+ handset with many more buttons to accomodate on the Denon handset, I was struggling to get all the functions learnt, and besides I found that the Denon refused to recognise the "Record" button. Then I tried using one of the two VCR sources.... not only did I then get play, stop, pause buttons etc on the Denon remote, the remote had no problem in learning the "Record" button from the Sky plus remote. In fact it learnt all the buttons fine, including the "Sky" button. Hope that helps someone out there!!
