..... Your DTR's may do the same as TiVo but they aren't triple tuner, no on demand, and less selection than M.
We can still record 2 channels while watching a 3rd on each of the DTRs
We don't care about On Demand at all, and have the M cable TV in a different room for any channel different from Freeview.
TBH there isn't that much on television worth watching most days, & when there is, it often arrives at the same time.
