I have been using a DCX3400 (500GB) for years without issue. Over the last few month recorded shows have been stuttering on playback. Programs stop, pause, skip a little and then start again numerous times while watching, often ruining the continuity of the show. Live TV looks great and works fine. I am not using an expander. The PVR is 60% full. Any suggestion on the cause and a possible fix would be great.
P.S. I saw another post on stuttering but the users had an expander and live TV was impacted. Not applicable in my case.
Thanks in advance
