I could try the reset. How do you do a soft reset? Is that unplugging the receiver? Assuming a hard reset is resetting to manufacture settings?
I think the problem is most likely the TIVO player. Tivo is basically obsolete. A bit of research on the Internet shows that Tivo are no longer properly supporting devices, and deactivating some. Cable companies are no longer required to support TIVO and many do not, so you have to use their DVRs.
So I suspect that either Tivo, or more likely your cable, or satellite company have bricked your Tivo.
The other issue is that it could be HDMI incompatibility after an update. Your Tivo is version 1.4 your TV HDCP 2.2. Now there is supposed to be backward compatibility, but I can tell you from personal experience there is not.
I think your problems will be solved of you get rid of the Tivo player. When you connect your Tivo to the TV repeater architecture is not required. When you go via the receiver it is. So my original hunch that your problem was a repeater architecture problem, was broadly correct. However I now think your issue is obsolete HDCP codes on the Tivo player. There is pretty much universal opinion on the Net it seems, that Tivo is basically done for multiple reasons.
