Help! We are having serious plaback problems on our DVR. We have a multi room DVR and a HD set top box in a different room. We record on the DVR often with no issues. However, when we record Teen Titans, my son's favorite show on Cartoon Network HD, the playback is a disaster. The show stops, pixelates, skips, sometimes it is very difficult to get through the show. It does not matter which TV we watch on, the problem is the same. We have reset the router with no improvement. Very frustrated five year old on hand....please help!!!
