I had this box. It has always had a fault where it would freeze playback for 25 seconds; we could live with that. Then it made recordings but would not play them. I phoned support and after going through all the usual palava I was told to do an reset. It crashed. So I was told I needed a new box. Not just a new box but full fibre with 150mbps, digital voice for my telephone and the new eero 6 router (which made my old router redundant) and a new 4k TV box.
Great! But in my opinion the box is much harder to operate that my old box. It records onto your own USB stick which must be larger than 36gb. Finding your recordings is much harder than your old box because, you have to press the up switch then the left switch on the menu five left clicks. I can no longer press the right switch to jump a recording forwards 4 minutes to skip through adverts nor the left to go back 15 seconds. Fast forwarding or backwards goes at x3, x10, x30, x100 and x200. It has a (presumably) stop button with a white square on it which noes nothing and also a button with an X on it that also does nothing. Strange.
One very good point for me, being colour blind: the four coloured buttons have R, G, Y and B on them. Full marks for at last recognising that some of us can't tell the difference between red and green.
Most of the instructions are online but you will have to do a lot of investivating to find out where everything is.
I did ask if I could just have another DN370T box but it is discontinued so I have just got to get used to the new 4k.
There is a mass of things to watch that I just don't need or want.
Talktalk, like other providers want everyone to be digital which is much easier to maintain so I think if you ask nicely they would convert your existing set up.
One final point is that the new eero router absolutely flies in my study but the speed drops significantly outside of the study. The solution appears to be solved by buying more expensive extension eeros.
