I've got a Tivo HD and looking at buying a 2nd one (another Tivo HD, not the new higher end one though). How does the Tivo Desktop software (free version is all I have and all I really want) work with multiple Tivo's. Looks like I can put only a single MAK into the copy of Tivo Desktop I have now. What do I have to do to be able to use the single copy of Tivo Desktop on my single computer with both Tivo's, both for pulling programs off of the Tivo's as well as acting as a server for either of them. Thank you.
