In reading a few of the threads that reference my question I'm a little confused. So I'm asking... can I can use (and which one) a TIVO box to record multiple off the air channels? And if so how many channels can I record, two, three four, etc? I'm really getting fed up with cable and satellite providers. Although I will miss some of the channels that are only available on said providers, if I can record some of the network programs that happen to be on at the same time, I'll drop them like a rock.
