Has Tivo come out with a universal remote of their own? I need something that will operate in priority: Tivo, Sony reciever, Sony DVD, Sony vcr, Toshiba Tv. Currently I am using my Sony reciever universal remote and have programmed the Tivo buttons on the remote, but when a guest use the remote they do not know what buttons to use. There are some universal remotes out there, but way too expensive. What is everyone else using?? I know the tivo remote will control the volume on my reciever and turn off my tv.
