Hi Simonkbike,
Welcome to the Humax forum. I know a lot about the Youview pvrs, as I am on the Youview community forum. What was wrong with your mum’s box? Which model was it? Hopefully it is easy to fix/reset. If your mum still likes the Youview menus, I would recommend either trying to restore box or purchasing another one online. They don’t
sell new ones now, but used/good refurbished ones can be found for a lot cheaper price. Ideally the 2100 & 4000 models.
The Manhattan box menu looks similar to Youview, but may lack functions. The Aura is a lot more advanced and maybe too complicated for your mum? If you could confirm what was wrong with the Youview box, I maybe able to answer your question, to save you money! John L
