I am trying to hook up my Tivo (which has a USB wifi card attached to it) to my computer (which also has a USB wifi card attached to it.) I do not have a router of any kind, but I was told I could still link the two wirelessly so I can transfer the programs off my tivo to the computer (i use the telephone line to do the updates) Is there a way to do this without a router? I tried to and got the my music and my pictures folder to link up, but I couldn't get the tivo to show up on my tivo desktop.)
