Hi All, I thought I would try the interval recording function of my HPX370 today, nice clouds rolling thru. I read the book and set up the camera, hit “record” and stepped back. Everything looks fine, “I-Rec” was flashing red, the, tally lights were flashing, TC was counting up. OK thats enough, I hit the “record” to stop recording...nothing happened! Everything was still flashing, TC still counting. I tried to access the menu...no luck...tried holding the “record” button down longer...no luck, finally I turned the power switch off and that stopped it. It recorded everything just fine. I tried several times, all with the same result. Has anyone experienced this? What am I doing wrong?
