The freeview tuners used in Humax and Topfield pvrs and the ones used in the Freesat Humax Foxsat-hdr can demux two channels at the same time from the same multiplex/transponder
This gives the following capability
If both the recording channels share the same mux/transponder then only 1 tuner is required for both recordings. The second tuner is completely unused so can be used to view any other channel and even on the hdr buffer it to the hdd allowing time shifting as well
If both tuners are using different mux/transponders then 3rd channel viewing is available from any channel sharing a mux/transponder as either recording is from.
Add to this the capability of the hdr to use both tuners with only a single lnb means that recording/viewing wise it's a lot more flexible.
In theory (and in practice on the Humax Icord) two tuners can record up to 4 channels at the same time
Believe it or not a Topfield Freeview pvr tuner with the aid of a tap can record a whole mux at the same time - you do need a big hdd though
