I've just got my second tivo up and running and bought the HNP. This is all working fine. I've renamed both Tivos - one for 'lounge' and one 'family'. The tivos now appear on each others Now Playing List, and I can transfer between devices fine.
What is strange is that each tivo appears twice - once under 'Lounge Media Device' and again under 'Media Device'. The same applies to the other machine where I see 'Family Media Device' and 'Media Device'.
Is that normal? How do I get rid of the double up?
Also what is the best free app for transfers to a Mac? I'm just wanting something easy to use with the ability to transfer the odd recording to DVD or to my iPad.
