Advertisements I undertstand from another thread that there is a fundamental limitation with some specific TiVo boxes, namely those with service number starting with 5xx. One of my boxes is 5xx. (The other is a 2xx box.) Could someone please point me to an explanation about why this box isn't as good as my older 2xx box? Should I be considering retiring my 5xx and just getting a new box (for free?) from TiVo as my "second" box? Is it still just the same price per month? I'd just have to make a 1 year commitment, correct? If the new boxes are unequivocally better, and free, and we would otherwise keep our 5xx for the next year anyway, isn't this a no-brainer??? I couldn't find a way to check this on the TiVo website... no way to see how much it would cost and what commitment I'd have to make with regard to adding a new TiVo onto an existing TiVo account.
