Thanks for updating the thread again bretta
Upgrading to the V6 box would seem to be the solution (although she would lose her recordings and series links, but she would also lose them if she went to an Openreach supplier as the VM boxes don't work with any other provider)
The V6 has the same interface as the tivo box that she has, so she wouldn't have to learn anything new.
It's also a lot faster, and has double the storage for recordings (although she probably wouldn't need it, but it would allow her to record 6 programs at a time instead of the 3 that's available on her tivo box)
The V6 also has some additional apps. The older tivo box which she currently has often has problems with BBC iPlayer - the V6 has no issues with that app.
