Having spent nearly 1hr on the phone, being transferred 4 times, cut off twice, I am taking a break from Customer Services and trying on here...
Setup: V6 Box downstairs, direct Ethernet to 2AC Superhub TiVo Box upstairs, Ethernet link via Powerline NOTE: Ethernet/Powerline all working as expected and multiple configurations tested without success.
Up until yesterday evening (and for last few months), could view/watch programs recorded on either box from either box. Worked as expected, no problems.
Last night, suddenly the TiVo box stared throwing up Error V106 "You cannot play shows from The Living Room TiVo Box as it is not in the same account" The V6 box also now states "The bedroom TiVo box could not be found" Error C423.
Rebooted both boxes and Powerline (several times) Changed setting (from another thread) for Remote Control to "Allow"
I see numerous postings regarding failure to get V6 boxes networking, either via WiFi or powerline, and/or intermittent operation. I am experiencing the same myself, and have spent hours with and without customer support's help, trying to resolve the issue. Customer Support staff appear clueless on the issue, as indeed do most of the Forum members in the community. For the sake of all of us, would VM either come up eith a DEFINITIVE statement on how to get this to work properly, or MAN UP and admit there is some fundamental problem. But stop saying "try this or that" just to placate people. If you don't really know how to fix it, say so and stop wasting people's time.
