“Can I record a TV show from Antenna TV while watching another show? We don't have cable, or anything fancy. We have just over the air, old fashioned antenna tv. We have a HD TV that allows us to receive singles and it is a new TV so it has the latest bells and whistles. Will this unit record shows from this tv? Will I be able to record one show while I watch another? Is it programmable so I can set it to record a show if I'm not home?”
