I would like to buy a Freeview PVR for my elderly father-in-law. It therefore needs to be very easy to manage and to set up. Recording needs to be fool proof. It would be good if he could record one programme whilst watching another. I was thinking of the Goodmans GHD8020f2, but Amazon implies that you can only record analogue whilst watching digital and visa versa. The review here does not seem to imply that. Which is right and any other recommendations?
