Don't know diddly about it, but rumors are my 3 kids are talking about getting it for me for Christmas. Son says there are only two types of people - those who have tivo and those who have never seen it in operation. Once you see it, you have to have it. Like honest evaluation, ideas, thoughts, etc. especially from those experienced with this. Sure this has been discussed before, but I was never remotely interested. Now, I guess, I am.
