I have 2 boxes (V6 and Tivo) but I can't watch recordings that are on the Tivo via the V6 and vice versa because I don't know how to connect things in order to do the multi-room thing, which is a bit disappointing sometimes.
You need to connect the TiVo to the hub with an Ethernet cable.

@Lee_R. Yes, the problems have gone away Lee, and all seems to be working as expected. I posted that earlier.
@SpacePhoenix. I know how to access other boxes. My problem was that I didn't know how to connect them. I could connect TO them once they were connected. I'd rearranged stuff a while back and never managed to reconnect the cables as they were.
@Roger_Gooner. Thank you for that tip. I did it and all is well now. I probably missed that because the Tivo was already connected to the hub via what I think is a coax cable. I'm pretty sure that I can connect both boxes to each other too. I did that originally, and I may have to again because the hub soon won't have enough network sockets when I add another Raspberry Pi to the internet, although I may be able to connect one socket to another router and connect more than one computer via that.
