I am considering buying a Humax DVD recorder, DRT-400, and want to understand more about how this unit will interface with my digital cable service. I have Comcast digital cable, which uses a cable box. Looking at the Humax setup instructions, it appears that I will need to run analog out from the cable box, and in to the Humax. Is that correct? Comcast offers a DVR unit that I believe is totally digital, but unfortunately lacks DVD-R. I want DVD-R, but am concerned about quality if I have an intermediate conversion to analog.
