At least saa713x and cx88xx boards can do DVB and analog at once for external inputs, if not depending on a single hybrid tuner for both, also DVB and analog TV from tuners. Else, they totally depend on software switching between those external inputs. In short, to have those inputs at once, you need at least two those chips per board and PCI hardware able to deal with them.
