said by Mac973:Comcast Moto boxes are almost identical to the FIOS boxes other than the MOCA capability. It works fine for me using the S-Video out and stereo audio cables into a Lite-On VHS/DVD recorder.
I assumed recording to DVD wouldn't work. My friend has Comcast and tried to record HBO onto a DVD and it wouldn't work (that was using a composite connection since he doesn't even have an HD tv). Maybe Comcast receivers are different.
