Just set up Channels DVR for the trial and it TVE service. I am already using an HDHomeRun Prime and cable card. Very cool. I'm not particularly technical and have seen some comments that suggest that there is a picture quality difference between the two. At first glance, I'm not seeing it which is I suppose the real test but was wondering if someone could explain the difference if there is one so I can judge which would be the better source for recording and viewing.
