First check out the first link to the dvrplayground post to set up HMO for viewing pictures from you PC onto the Tivo. Second is how to set up so you can watch videos from your PC and watch/convert them to watch on your Tivo. Third is to download, edit, and record onto DVD the shows from your Tivo (Two seperate links.)
Once you have all this running you can also set up MRV which is the best part of having 5 D Tivos in my house. I can watch what is recorded on any of the other D Tivos. Second is I download the movies/shows and either watch on my XP or Vista Laptops then convert to an MP4 format to save/watch the movies on my PSP at work.
