We just set up the unit. I can play videos, but when I go to playback videos after trying to record from t.v. all I get is black space. I found the button to set the time and timer record. I did not see anything on display to set channels. also we set it up through a converter box. We have playstation and direct tv. set up through the unit. When I want to watch a video or dvd or play my video game I have to switch the converter mode to antenna.
