Record Show Watching Another Cable Box Vcr With A Digital Tuner Can I Record A Show On VCR Using A Converter Box While Watching Another Channel On Digital Tv Via Roof Antenna?

Can I record a show on VCR using a converter box while watching another channel on digital tv via roof antenna? - record show watching another cable box vcr with a digital tuner

I want to be able to use my recorder to record programs while I'm at work. Do you know whether it is possible to see for my family, digital TV or a DVD, while some other TV show I'm recording with the VCR connected to the converter. You know what the parameters that are associated with cables, etc. Thanks
