If you have a DVD recorder as part of your TV setup, there is a copy function which records programmes realtime. Alternatively you can use a TV capture card to do the same thing to a computer, again in real time. A quick search on Google will give you some solutions. I looked the other day as we were going to have our box replaced and would lose everything on the old box. Unfortunately there is no way of just dragging and dropping from one HDD to another.
