MRV between TiVoHD DVRs each with lifetime subscription service?

[fred-vo]

I have one lifetime TiVo HD DVR.

If I purchase a second lifetime TiVo HD DVR and put both on the same wireless in-home network, will I be able to do MRV (multi-room viewing) between them?

A TiVo webpage, http://tivosupport2.instancy.com/LaunchContent.aspx?CID=1e643fc9-446a-436d-86cb-8661b81991a5, says
"The DVRs must be on the same TiVo billing account"

So, I guess I am asking if two lifetime TiVo's in the same in-house network are considered to be on "the same billing account" for the purpose of determining MRV capability.

Yes.

Actually no. They need to be on the same account, to get the same MAK, and have the same MAK to MRV. The fact each has its own Product Lifetime doesn't matter.

But if for some reason they're not all hooked up to the same account, you can call customer service and have them all put on the same account.
