TalkTalk no longer provide recordable boxes and haven't for 4 years now.
On the retail market the only recordable box is the Freeview play one by Manhatten. This the T4R.
On the grey market you can obtain an EE (BT) Pro box. The benefit of this is the ability to record 4 programmes simultaneously and it has the YouView functionality you will be used to.
If you decide to go town this route you will need to phone to request the removal of the TV charge and request a returns bag.
Please remember to mark Solved Posts with Best Answer. Doing so helps other customers and saves TalkTalk's Support Team time by only looking at unsolved topics. Thanks, Steve (a fellow customer).
