I was watching a program on my built-in DVR this morning. Several times, ten or so, the program sudddenly did sort of what it does if you hit pause and then fast forward: it cycles jerkly forward with no sound. But there was no information box like if I did it myself. I would immediately hit reverse and then play; it would redo the last couple of seconds and go through where it had that problem. I few minutes later it would do it again, with the same "solution."
That has never happened before. Any ideas what happened?
