Now, here's how it works. Obviously, the regular cable feed goes into the TiVo for all the basic features (watching TV, Recording TV, etc). If I turn the VCR on, it takes over what the TV is showing (either the feed from the TiVo or the feed directly from the switch box (or, I guess, a VHS tape)).
Now, in order to get the TiVo to recognize the incoming A/V feed from the switch box, I have to change the TiVo channel to channel Zero. The A/V-in on the TiVo is supposed to only be used for a Digital Cable Box, so what I'm doing is techically unsupported. Anywhoo... If I have either the DVD player or the GameCube powered on (and it's button switched on the switch box), I get the Audio/Video feed both live through the VCR or on the two second delay through the TiVo feed.
However... If I try to use the Nintendo 64, the Super Nintendo or the original NES, I get the live feed through the VCR, but the TiVo tells me there's no A/V feed coming in and to check the signal, etc., etc... So I tried switching connections, putting the N64 connection into the switch box where the GCN was connected, connecting the SNES directly to the TiVo... everything... But the TiVo just won't recognize that it's getting feed from the three older systems... Any ideas?
