any TiVo geeks?

[hiker_chick]

My TiVo won't recognize my cable signal anymore. I know the signal is good because I can route it through my (old) VCR and watch it on the TV. Perhaps the coax jack or the tuner itself is busted? Any ideas?

If it's the coax jack, might I be able to get a coax to S-video converter at, like, Radio Shack? Wishful thinking or likely solution?

Thanks in advance.
