A receiver, such as an HDTV receiver or a Personal Video Recorder (PVR), includes a plurality of tuners. Each tuner is adapted to receive television signals (RF1,RF2) comprising a plurality of channels and communicate the received television signals to a processor. A channel search or autoprogramming routine is disclosed for the detection of channels in the television signal wherein each tuner simultaneously tunes and interrogates a different channel in order to expedite the search. If a signal is not detected on a channel, that channel may be tuned and interrogated by a second tuner. A list is compiled of all the channels that contain a television signal to aid the viewer's selection.
