Okay guys, I am considering getting a SKY+ box, to take advantage of their current offer. Before I take the plunge I have a few questions: 1. Can you upgrade the hard drive? 2. Can I dub from the hard drive to my DVD recorder discs? 3. Can I dub from my hard drive to my Archos player? 4. If the answer to questions 2 and 3 is yes, what sort of dubbing speeds can I expect?
