Given the problems I've had with my CableCards, I don't know that Doug would want that headache.

That said, I imagine the problem might be in all the processing that's going on. Cable to S-Video to MPEG to component to LCD is quite a few steps.

The first thing I would do is plug the cable box directly into the TV and see what that looks like. First do S-Video and then try anything else it might have, especially HDMI.

Do the TiVo menus look okay or are they low quality, too?
