I hope these are the right answers. The wires are overwhelming...
* brand/model Tivo? TIVO S2 Model 540140
* brand/model TV? Quasar
* what's your video source (cable, cable box, satellite box)? Cable Box
* how is that video source connected to your Tivo (cables, connectors, inputs/outputs)? RF Out
* how is the Tivo connected to your TV (cables, connectors, inputs/outputs)? RF IN and and AV (R\W\Y)
Again, everything else works. Also, I tested a recording with the TV on and it works. I hope that narrows things down.
