You would use an S-Video and left/right audio cables. But I strongly recommend renting a second, standard-def cable box for the Tivo to use, as you will otherwise compromise your use of the HD box for viewing HD.
I have the Motorola 6200 box. I have the ir remote on the the right side of the clock. Also to fix the IR changing problem I disabled the 3 numbers than enter code. Currently if you put in just 2 the box turns to 2. I have not had a missed show yet because of the channel not changing.
Using a comcast box. Go to main menu. In the main menu ther is a menu item showing as Auto Tune. Once I did that if I want to turn the channel to channel 6 I just hit 6 and it switched to that. Before I had to do 006 (enter) Works like a charm.
