30 sec gaps in continous recording

Why can't I get continous recording to work on one camera. The other three work fine. In fact this camera was working fine before I installed two more cameras. During playback there appears to be a 30 seconds of none after a gray patch or a blue patch.

After a little testing. I switched cameras. The problem stayed with the location. The camera that was skipping 30 second now is working. The camera that was not skipping now skips. I moved the skipping camera to another channel and it still skips.

after more testing I realized that I had updated the firmware from 3000_211 to 300_226. So I found the 300_211 firmware and down graded. This did not correct the problem.
