It turns out I'd wrongly blamed a power cut that never happened on my loss of home machine. In fact, it was my poor little 3Com wifi enabled router which had got its knickers in a twist and needed a restart. Still, it generally behaves really really nicely, as does its little brother the 3Com wifi travel router which provides TiVo with its connectivity. I think I've only had to power cycle the big one twice and the little one never. They Just Work (FSVO"justwork"that seemed to involve a lot of pain to get the little one to do the right thing initially).
