recording dvd from dvr
I have a Time Warner Cable Box with DVR as part of the box. I have the capability of recording several hours of progamming. As the programs are recorded they are put on a list, latest first and then you can view them at your leisure. Shortly, I will buy an HDTV and will have to change the cable box. I would like to pick out a few of the saved programs and record them on a DVD. I have a combination DVD/VCR recorder that I just purchased. I tried to do this without results. Although I did get the audio part. Does anyone know if and how this can be done ? Thanks.
