Back in 2004 my wife and I received an SD Directv TIVO and it lasted us until we got an HD set and had to move to a Directv HD DVR. After a few years with the DirectTV DVR and issues with this particular model (slowness on buttons) in late 2012 we moved back to the Tivo HD DVR. Only complain I have is that it likes to record its enhanced content at certain times of the day. Any way I can change that? Doesn't seem to be a problem back in the old tivo days.
