Has anyone ever got to the bottom of the tivo/V6 box video output settings mystery?
Why do the boxes love 720p so much, if you tick every output and go into the supposed native mode 720p comes through, when surely for HD here in the UK it should switch to 1080i, and for the tennis on Eurosport4K it should switch to the 4K resolution.
Surely someone out there knows exactly how it works and what it's doing.

Thinking about it, makes me wonder if Virgin are scaling the 1080i and maybe even the 4k to 720p at their end. Hence when you tick all the outputs you are presented with 720p. How crap would that be if the case.
