I am planning to spend the summer at my second home. I will take my Tivo Premiere with me so I can record off the air, but I would also like to be able to transfer shows from my home Tivo (uses cable broadband) to the Tivo I will have with me for the summer (using DSL). Is this possible using Slingbox? How well does the data transfer--does it have to go to a PC first? Is there any other way to transfer recordings to my "on the road" Tivo from my home Tivo?
