scuwp: It's been a while, but my understanding has always been that unless you had the HNP, each TiVo was effectively a stand alone device.  I have 2, and don't have the HNP, and there is no way that one device can see or play content from the other.  As the HNP is no longer available you are out of luck.

I am pretty sure we (NZ) only have the series 1 devices, so the above link doesn't apply.   

We have the series 3
