I have had this fault for ages and tried to resolve it myself. Eventually phoned to get it fixed today. After the customer services tried remotely, I was told it was a hardware issue but won't get an engineer for a week. This has went on long enough and I'm reluctantly now going to contact Sky to see what they can offer. I have had a few issues with this TiVo box and have no confidence in it anymore. It is now asking for my pin to watch ITV daytime!!!
This seems like a big issue with multiple boxes, what you could do if it's a hardware issue is request for a quickstart kit, as they take 1-2 days (in my experience) to arrive, which would be quicker for you.
Also, from previous experience negotiating with sky, and moving from them, they will not provide as well a price in most likelihood, but it may be worth speaking to retentions to negotiate a better price or something as compensation for the issue with their box.
Hope the issue is fixed soon.
