My DCS-5010L (firmware 1.01) will out of the blue send corrupt jpeg frames. I have two of them, and they both do it (not synchronized, they'll do it independently).
They are both wired, so this isn't a wireless interference issue.
After a second to three of sending corrupt frames, they'll reset themselves (send NOTHING), then back to normal service. This is making motion detection using these cameras
completely useless!Here's an album showing the corruption (three corrupt frames, plus a good one at the end):
