I have fond that its not the DVR box, it's the sync of the boxes and correct connections of lines to outlets. Coding on Comcast part. Deep layer code, not survace. Correct booster placement and even amount of feed going to all lines. Tolerance range is critical to reduce feed back and excess noise suppression. Exterior cable to hub box, if more than 5 years old may need replaced. The ratio of nodes to homes on that node is a major factor. Too many homes, reduced signal. Thus X-1 Will not work correctly. I've spent 11 months working and training techs that come to work on system to get it to work. My request to Comcast is for each field tech to have an X-1 System for free at their home, thus they can train themselves on system. This will let them troubleshoot issues and help resolve customer issues before they go to competitor.
