I do not have cable or any other pay TV. I have a regular old tube TV in a workout room. I want to buy a DVD/VCR combo not expensive but have been told I have to have a built in tuner. If I am not concerned at this point about the 2009 changeover and just want to rig this and be able to record programs to watch while working out what are my options. Do I have to have a built in tuner?
