The TiVo needs to be connected to the Superhub with an Ethernet cable.
However, this only enables the TV Anywhere app to be used as a remote control for the TiVo, all the other features of TV Anywhere (managing TiVo recordings, streaming live TV etc.) should be available without this connection. Bear in mind that some channels cannot be streamed, only the ones that can have a small "wi-fi" icon next to them in the guide i.e. Channel 4.
I think you have to use Sky's own apps to watch the sports and movies, they have a special log-in option for VM users. For the BBC you have to use the iPlayer app. The availability of other channels varies, as I said, look for the Wi-Fi icon next to their name in the guide.
And yep, the connection doesn't add much, but if your TiVo is near your superhub you might find it worth cost of cable as they're less than a pound on eBay\Amazon.
Thank you for taking time to reach us, i hope you're enjoying the weekend so far
