I agree with the above post. Most people struggle with a video recorder on its own, having to program the video + a box (let alone wire it all up) is going to be too much for many people. And if their tv is also analogue, they will need yet another digital box if they want to record one digital channel while viewing a different digital channel at the same time (like they did with analogue).
...tapes are going out fast anyway. Many people will take the switch to digital as an opertunity to switch to some type of digital recorder anyway (DVD or hard disc).
