I want to hook me tivo remote up to my tivo so i can control my volume on my tivo but tivo wants a 4 digit code for the TV, and the tivo "suggested code" isnt right so it says consult the manual of your tv. Well TV's all have 3 digit universal codes? How does this work??? I have an Advent Q2035A Flat Screen TV. Anyone know what i can do ive vigorously searched my TV Manual with no success. Thanks
