Without knowing exactly what connections your TV etc has, and exactly what you want to do, it's hard to advise. But my best guess would be something like:

In living room:
TiVo->TV#1 (HDMI)
TiVo->sender (SCART)
DVD/VCR->PVR->TV#1 (SCART)

Then upstairs:
sender->TV#2 (SCART)

You'd need to use a SCART splitter if you also want to record on the PVR from the TiVo or if TV#1 doesn't have an HDMI input.
