My VIP722K does this periodically. At the same time on OTA broadcasts (only), when watching them live but delayed will hesitate and move on with the forward arrow briefly showing up on the screen and a loss of a fraction of a second of sound. When I press skip forward it says it is live. I have to press skip backward and the skip forward to move forward in time. The other day the failure occurred when watching a program being recorded. At that point the DVR skips back a few seconds moves forward until it hits the drop point. This proceeds on an endless cycle unless I stop it. At the end of the record time which says it has recorded the entire program, it quits when hitting that drop point. I've keep this recording should anyone from Dish want to see it. If I reboot the machine it may work for a while without this pausing issue, but then it occurs again a little while later. It is making it difficult to what live delayed programs with the OTA tuner. We had this problem with our older VIP722 which was swapped out because of the problem, but the VIP722K seems to behave the same.
