When I hang out in airports I typically buy a magazine to occupy my time.  This trip, just like my last trip, I bought Macworld.  There are a lot of interesting reviews and other interestingness in them.  In this issue, there was a review of a great freaking program to help Apple users use there Tivo just like windows users do.
You can connect to you Tivo and download them to your computer.
Right now I am testing TivoDecode Manager for the first time and so far it is working fantastically.  All told it should take about an hour and a half to download a one hour show over my wireless network.
Updates to follow.
